From “Deep-Sky Wonder’s” By Sue French:

“Moving back to Omicron and dropping 2.7º south-southwest takes you to a golden 7th magnitude star. It ornaments the eastern side of Webb’s Wreath, a little-known asterism first mentioned in the 4th edition (1881) of Thomas Webb’s observing guide “Celestial Objects for Common Telescopes.”

My 105mm scope at 68x reveals 13 additional stars, magnitudes 11 and 12, outlining 11′ x 7′ oval leans northeast and is dented inwards at the bright star.”

RA: 18h 02m Dec. +26 18m

6-09-01: Telescope 105 mm Apochromatic refractor; 610 mm focal length, and a 9 mm Nagler eyepiece for a magnification of 68x.

Pencil Sketch by Sue French as following: The following sketch was made using my 105 mm refractor with the employ of a diagonal.

Images by Mario Motta:

Using my 32-inch telescope, I imaged Webb’s Wreath in RGB and Lum, subtle colors. The images as following present the Wreath with north is at the top and west to the right.

The following image identifies very faint galaxies inside and around the wreath.

Can you still spot the galaxies in the following image?

Observer’s: Keith Rivich and Larry Mitchell

Location: ~10 miles SE of Leakey, Texas

Telescope:  25-inch f/5 Newtonian

SQM-L:   21.3

Seeing:  4 of 10  (Seeing pretty much was limited to around 300x, however, could occasionally go higher.)

Transparency:   10 of 10   

Webb’s Wreath itself is a worthy target. My 20 mm Nagler eyepiece framed the wreath quite nicely looking a bit like a lop-sided potato. Larry was going to check GAIA to see if any of these stars may be related. Except for the 7th mag star the rest look suspiciously similar. 

UGC 11097: 

This galaxy was just out of the frame in the (Mario Motta’s image) but I used it as my star hop base, so I will go ahead and mention the observation. Easy to see at mag. 14.5 with a pretty high surface brightness. Its 1.2′ x .3′ nearly N-S elongation was obvious being brighter in the center and tapering off towards the ends of the arms. A couple of 15th mag stars bracket the galaxy.

PGC 61289 (MCG +4-42-22)

This is the brightest of the galaxies in the Motta image. As suspected at mag 14.6 it was quite easy to see, appearing as a very small oval glow. A mag 14 star sits just off the galaxies northern edge.

2MFGC 14178 (in the image as PGC 1768412)

As suspected this one was tough and fun. When the field first slid into view I strongly suspected I could see some elongation at the right spot. Looking at images there is a 15th mag star just 20″ east of the core of the galaxy, which is depicted as a 14th magnitude “non-star” in Megastar. These two “stars” could easily mimic the elongation I was seeing. I bumped up power to 650x and during moments of good seeing I could distinctly see the arm of the galaxy opposite the 15th mag field star. I called Larry over to take a look and he was seeing what I was seeing. As a bonus he knew nothing about the galaxy before looking. 

For the fun part of the observation we put Larry’s NVD into the scope. He had it mated to a 27mm eyepiece so the magnification was quite low. We suspected the NVD devise should work as the galaxy is infrared bright, and we were right. The 15th mag field star was dramatically reduced in brightness so the galaxy, though tiny, was just visible as a complete edge on spiral. The dark lane visible in high res images was not visible to us. 

LEDA 1772537 (in the image is listed as a PGC):

As suspected nothing. Nada. Not even a sparkle!

UN-NAMED FACE ON SPIRAL:

We couldn’t see anything of the galaxy, no surprise there, but we could see the 17.5 mag star that sits on the NE edge of the spiral. 

Observer: Roger Ivester (North Carolina)

The following pencil sketch was made using a 10-inch f/4.5 EQ Newtonian with an 11mm eyepiece, apparent field of 82º. Magnification: 104x and field-of-view of 0.79º which was a perfect framing for the asterism.

As a follow-up on the four galaxies in and about Webb’s Wreath, they were partially featured in Stephen O’Meara’s column in the May issue of Sky & Telescope (p. 12).  Keith’s and Larry Mitchell’s earlier observations of PGC 61289 and PGC 1768412 with Keith’s 25″ were discussed in the article.  O’Meara also mentioned the two fainter galaxies within the Wreath itself “most likely require even larger apertures to detect.”  One of these is PGC 1772537, an E- or S0-type, and the other is a spiral not catalogued in LEDA (PGC).

The following is a Cloudy Nights post by expert big scope “visual” observer, Steve Gottlieb

Larry Mitchell also included Webb’s Wreath and its galaxies in the Texas Star Party’s “Advanced Observing” list, just a week ago.  When Larry came over last Thursday to observe on Jimi Lowrey’s 48″ f/4.0, he requested to look at Webb’s Wreath again to search for the two dim galaxies within the Wreath.  Also observing with Jimi and I were Stephen O’Meara, Brent Archinal (from Lowell Observatory), and Doug McCormick (from Houston).

When we observed these galaxies at the end of the observing session, the background sky was jet black in the eyepiece (excellent contrast) and the stars pinpoint at 610x. The unnamed face-on spiral (NED lists the infrared designation WISEA J180231.28+262057.6) was immediately seen as a faint, very small glow, perhaps 10″ in diameter.  Although it was fairly easy to see, the visibility may have been enhanced by a faint star at the NE edge.

PGC or LEDA 1772537 was easy to pinpoint, as it lies at the midpoint of a mag 10.8 star 40″ SW and a similar star 40″ NE (two of the main stars in the Wreath).  At 610x it was very faint and quite small, perhaps 5″ diameter, but definitely non-stellar. I may have just been seeing the core region of this galaxy.  Checking later, I noticed that HyperLeda lists a B magnitude of 17.93 ± 0.50 and NED list a single redshift at z = 0.192.

So, there’s two things interesting about LEDA 1772537.  It lies precisely along the Wreath, and if the redshift is accurate, the light of this E or S0-type galaxy has been traveling for 2.4 billion years! (using H₀ = 70).

Yes, the 6-inch f/6 Newtonian in my opinion, just might be the perfect telescope for the dedicated visual observer. It’s both compact and lightweight, and even with an equatorial mount is easily manageable, and has twice the light gathering power of a 4-inch refractor.

I had a 6-inch Criterion RV-6 almost 50 years ago, but life got busy and sold it. However, I always regretted selling that telescope. So, in about 2017 I bought another 6-inch, but this time with an f/6 focal ratio. The Criterion RV-6 was an f/8. I like the f/6 much better as it’s a bit more versitile, for a wider field of view, and a 2x Barlow can make the f/6, an f/12. And the f/6 is more portable due to the shorter OTA.

I also have a 4.5-inch f/8 Newtonian that was given to me a few months ago, that I plan to use tonight to observe T Corona Borealis field.  

After being a serious “visual” observer for at least 40 years and having more than 10 telescopes, I’ve come to the conclusion:  A 6-inch f/6 Newtonian (my opinion) might just be the perfect transportable “visual” telescope.   

I can also use a GoTo mount with this telescope.

Photographs From Days Past Of Ivester Family And Events: Volume One

Photos by Kerri Adams: I reviewed all of the photo files and selected as best as I could, only a few as following that might be interesting to all. Roger Ivester

Following photo: Velus Ivester (August 7th 1877-October 28, 1966) and wife Rebecca (Mar. 27, 1891 – Oct. 6, 1965)

First wife: Zula Edwards Ivester (Dec. 24, 1879 – Nov. 14, 1919)

Veterinarian in the buggy, who Carl Ivester interned with to become a practicing Veterinarian.

Twins (?) ….one of which would train Carl or mentor, to become a Veterinarian. Carl did a “multi-years” apprenticeship with one of these men.

F.V. Ivester and unknown person. The beginning of a store that would serve the Upper Cleveland area for many years.

Velus trading two older AC tractors for two new CA Allis-Chalmers Tractors. (Circa ~1954/1955). All of my older brothers were in this photograph, sitting on the tractors. I’ve heard this photo was in the Shelby Star.

(Note: Text and identifications precede the photographs in all the following)

F.V. Ivester and wife Cleo: The store in later days (as shown) became more than a store, but a meeting place for everyone in the local area. Any local news happening? This was the place to find out.

There was always a Shelby Star available in the store for anyone to read. The store was heated by a large coal burning heater with the coal pile very close outside.

On cold wintry days with snow or ice…seems that almost everyone would want to go to the store for serious discussions, such as, how bad the weather was. It was very important to get the thoughts from others. 

However, the real reason: Everyone just wanted to get out and drive in the snow or ice. Snow and ice always seemed to bring out the kids in most all adults…all the while, pretending they hated it.

Photo 3: Possibly Ruth Adams as a child? Unknown person holding her. The smaller building was where wheat and grain was stored. The building to the right was an addition to the “old log barn.”

More about the building, and other buildings and barn later…

Reunion event at Kistler’s during Christmas 1955, in front of what was then known as “The Hut.” The Hut was were so many events happened when I was a kid growing up. The MYF (Methodist Youth Fellowship) met…seems it was on Thursday nights. And we would have a big Halloween event each and every year in the hut!

Kistler’s Church and the hut: Glenn Johnson who played Santa Claus on the night of our yearly Christmas plays. I thought he was the real Santa Claus, however, as I grew older, it occurred to me it was Glenn!

I’ve always said: “When you find out there is no Santa Claus, life is never the same…and not for the good.”

The Christmas play was in the church sanctuary in an empty corner, which now has a pew, or maybe the piano. Normally F.V. would remove his pickup wooden railings to use for the Nativity scene. He would also supply a few bales of hay for the manger area. We would begin practicing, normally a week or so after Thanksgiving.

69 years later: The following photo was made Sunday August 4th 2024, inside “The Hut” but now called the Fellowship Hall.

Articles by James Mullaney as following:

Don’t Forget The Finder! Date: June 21st 2024

The most embarrassing moment in my more than 60 years as an amateur and professional astronomer came one morning in the early 70s.  As the tour guide at Pittsburgh’s Allegheny Observatory, I was speaking to a group of 60 schoolchildren in the dome of the famed 13-inch Fitz-Clark refractor. 

My topic solar safety: how dangerous the Sun is to look at without a proper filter, whether it be with the naked-eye and especially with binoculars or a telescope.  I was near the top of the observing ladder projecting the Sun’s image onto a screen across the room.  As I was speaking, a little boy kept calling out my name:  “Mr. Mullaney, Mr. Mullaney, Mr. Mullaney.”  He was definitely running my spiel and finally in frustration I shouted down the ladder at him WHAT!  He said “Mr. Mullaney, your jacket is on fire!”  Sure enough, I hadn’t capped the 4-inch finder and it focused the Sun right onto my jacket – which was now smoldering. 

The Finest Deep-Sky Objects DSO at Mount Palomar:

Thirty-three years ago, my wife and  I were privileged while on our honeymoon to be given a behind-the-scenes private tour of the Palomar Observatory facility.  In the control room for the 200-inch Hale reflector was a dogged-eared copy of the Sky & Telescope reprint of  “The Finest Deep-Sky Objects” by Wally McCall and myself.  The story-line is that no one ever looks through the 200-inch except for research purposes since time is very valuable on the scope.  But apparently someone – maybe several someones –  had been using our showpiece list to look at between “takes.” 

Can you imagine seeing the Orion Nebula, the Hercules Cluster, or the Sombrero Galaxy at the prime focus of this huge Big Eye?  (BTW – while on the floor of this mammoth instrument I actually hugged part of the mounting!)

Sir William Herschel used a magnification of 6,000x !

Sir William Herschel, the greatest observer and telescope-maker in history. He made and used the largest telescopes in existence up to his famed “40 foot” (48-inch aperture) but his favorite was his “7-foot” (6.2-inch aperture) speculum-metal mirror with which he discovered Uranus. 

While he used relatively wide fields (for that time period) and low powers (generally 400X or less) for his legendary sweeps of the heavens. However, for the Moon, planets and double stars…the unheard of magnifications of over 6,000 times were sometimes employed ! 

Despite his fame, many “or most” doubted his claims regarding the magnifications he sometimes used.  W.H. Stevenson actually measured 48…yes 48 of Herschel’s eyepieces and found that indeed his claims were valid. 

Focal lengths as short as 0.2-inches to just over 0.01-inch were found!  How Herschel ever managed to make them is somewhat of a mystery.  (He actually used 6,450x once on Vega and also again on Gamma Leonis.)

No Star Diagonal?  Ouch!

With the exception of reflectors, most of the classic observers of the past used refracting telescopes. I really don’t know when star diagonals first appeared, but all of the early observers were viewing “straight through” their scopes. 

For low declinations this wasn’t so much an issue but for objects high in the sky, or overhead, it was a neck and back breaker.  And this didn’t just apply to amateur observers, but professionals alike.

E.E. Barnard (Yerkes 40-inch), Aiken (Lick 36-inch) and Lowell (24-inch) all worked without diagonals.  In the more than 40 years I used the superb 13-inch Fitz-Clark refractor (see my the great lensnapping piece below) at Allegheny Observatory I never used one.

One of the problems is the mirror image views, of standard star diagonals, which plays havoc for measuring double star position angles among other issues. There are now, of course, correct image, known as “Amici Prism Diagonals” but early observers didn’t have them.

The most shocking example came to me when I realized that my dear friend and one of the greatest observers of all time, Leslie Peltier, never used a diagonal to make his more than 120,000 variable star estimates for the AAVSO. He used his 2-inch spyglass, 4-inch Mogey refractor, 6-inch comet seeker or his 12-inch Clark refractor. However, Peltier used only the 4-inch and 6-inch scopes for comet seeking, as well as variables.

A Mystery Surrounding NGC 6826 Better Known as: “THE BLINKING PLANETARY“

Wally McCall and I first called attention to the strange behavior of the planetary nebula NGC 6826 in Cygnus in a letter to “Sky & Telescope Magazine” and was featured in the August 1963 issue. 

As seen in the 13-inch Fitz-Clark refractor at Pittsburgh’s Allegheny Observatory, it has a bright central star surrounded by an obvious nebula.  Staring directly at the star itself, the nebula disappears – but changing to averted vision the nebula reappears nearly drowning out the central star itself!  Alternating between direct and averted vision results in a striking blinking effect, so we named this object the “Blinking Planetary.”  We’ve seen this effect in scopes as small as a 2.4-inch refractor and as large as a 30-inch refractor.  A few other planetaries exhibit this behavior, but none anywhere to the degree as this one.

Now here’s the mystery: 

My idol Sir William Herschel (who discovered this object), nor his son Sir John nor any of the early classic observers like Smyth or Webb apparently ever noticed the blinking.  Has something changed in the nebula itself to shift its emission lines into a part of the spectrum where the eye is most sensitive since its discovery? Jim Mullaney

MAKING THE PHOTON CONNECTION

Roger, I feel sure that most of your readers are aware that the photons which we see by have a strange dualistic nature…they are both waves and particles.  This means that when you observe a celestial wonder such as those Roger writes about on this site with your telescope, you are getting photons within your eye.  

Think about it…particles that were once inside of the galaxy you are viewing have traveled across the vastness of space and time and ended their immense journey on the retina of your eye.  You are in direct physical contact with what you are looking at! 

As the poet Sarah Teasdale said:  “I know that I am privileged to be witness of such majesty.”

Stargazing Simplified: What to See in the Night Sky

The “Great Lensnapping”

Roger, I don’t know how many of your readers have heard of the “Great Lensnapping” that happened at the original Allegheny Observatory in Pittsburgh in the late 1800s.  

My beloved 13-inch Fitz-Clark had it’s objective lens stolen and held for ransom.  At the time, it was the third largest in the world!  (Now it’s the third largest in the current Observatory.)   

Samuel Pierpont Langley was director at the time and refused to pay anything, as no telescope in the country would then be safe from theft.  He finally met the thief at a hotel in a Pittsburgh suburb – the thief agreed to return it if Langley didn’t prosecute.  He subsequently found it in a waste basket at that very hotel.  

The lens was pretty well scratched up and Langley sent it to Alvin Clark for refinishing.  Thus the dual name Fitz-Clark.  As I’ve stated before, it is without question the finest visual telescope I’ve ever seen or used bar none!

To read more and see a photo of the famous 13-inch Fitz-Clark refractor, see the following link:

https://sites.pitt.edu/~aobsvtry/fitzclark.html

This is the telescope that Wally McCall and I used for our visual sky survey in the mid-60’s that resulted in the Sky & Telescope series The Finest Deep-Sky Objects and its eventual Sky Publishing reprint that went through three printings.  My personal total eyepiece time logged using this amazing instrument over many years was some 10,000 hours!   It clearly showed markings on several of the Galilean satellites and spiral structure within Jupiter’s Great Red Spot.  One of the “discoveries” we made using the 13-inch was the “Blinking Planetary” in Cygnus (NGC 6826) which has become a favorite showpiece at star parties and public viewing sessions. 

“The Finest Deep-Sky Objects by James Mullaney and Wallace McCall”

“On Public Nights at Allegheny Observatory, when the dome of the 13-inch refractor is crowded with visitors, all anxious to look at everything in the sky, a handy finding list of impressive objects is invaluable.”

These words prefaced our short list of celestial showpieces published in the December, 1962, issue of “Sky and Telescope”.  We now present an expanded version, intended as a roster of the finest star clusters, nebulae, and other deep-sky objects, for the convenience of amateur astronomers with telescopes of all sizes.  It is the result of our five-year visual survey of the heavens north of –40º declination.

Supplemental and change to an original post from about three years ago: July 7th 2024:

A few nights ago (July 2nd) while observing some asterisms, star images were ragged and would not properly come to focus. It was exhibiting the classic problems of pinched optics. The telescope had worked fine over the years, but I’d never taken the mirror out of the tube. However, on this night when the problems began, it was in the mid-80’s. Really hot!

So, the next day I removed the mirror and discovered that the clips were indeed tight. After a mirror wash, I reinstalled with care.

Using the corner of a sheet of notebook paper as a gauge:

I used a sheet of notebook paper to carefully slide between the mirror clips and the mirror, before lightly tightening the dual screws on each of the clips. This insures that the mirror has room allowance for expansion with changes in temperature, especially on hot summer nights.

Then using a Cheshire collimator and a follow-up using an artificial star (Christmas ball about 100 feet out in the backyard) and a bright sun. Everything was ready for another night sky observing session.

Defocusing a star both inside and outside of focus, presented almost identical and very smooth rings. A good mirror, especially for a mass-produced telescope. This OTA was made in Taiwan, which is producing some really good products these days.

Taiwan has taken over the very “high-end carbon fiber” bicycle market. And I’ve been told by some race engine builders, Taiwan has some fine and very modern CNC metal working machinery…possibly some of the best in the world. A $50,000 race engine cannot use substandard parts, and many race engine parts now come from Taiwan.

Now back to my 6-inch Newtonian:

I’ve always liked Newtonian’s because of their simplicity, and most amateurs will agree that a “good” 6-inch can be a very versatile instrument. Good for both visual (and with an f/4 focal ratio) excellent for imaging.

With the extra purchase of a nice quality 8 x 50 finder and stalk, a 13-inch Vixen narrow-rail dovetail to allow better balance of the telescope, and an extra ~10 pound “Vixen brand “counterweight.

An essential product for all Newtonian’s: A set of “Bob’s Knobs” for adjusting the secondary mirror. I’ve been pleased with this telescope.

The sky was very stable in the very morning hours, as I was anxious to see how the telescope who perform. My first test was the double-double as it was in good position. Very nice! I then tested with a few other stars, using both very high magnification and then observing some asterisms with low magnification. All looked good.

What a difference using the corner of a notebook paper edge under the clips, and then lightly tightening the mirror screws made. So, I took the telescope and mount back into the house with a smile, and ready for my first cup of coffee. Then it was time for an early morning bicycle ride. Life is good! 🙂

My second telescope in the late 70’s was a Criterion RV-6, which was really a step up from my 4.25-inch Edmund EQ Newtonian. Life got busy and I sold the RV-6 and then took a five year hiatus, or maybe more from amateur astronomy.

Becoming a “very serious student” of amateur astronomy with a 10-inch f/4.5 EQ reflector in February 1992. The 10-inch became my most used telescope with about 2,500 hours at the eyepiece as of 2024. Then in 1997 purchasing a 102mm refractor, and a 6-inch f/6 Newtonian in January of 2017. Then an 80mm f/5 refractor as a birthday gift from my youngest son.

When I first became interested in amateur astronomy during the late 60’s and 70’s, the 6-inch reflector was definitely the most popular telescope for the backyard observer.  

I really missed having a 6-inch Newtonian, especially for certain deep-sky objects, and portability. So, I saw an advertisement for the 6-inch f/6 Newtonian OTA and bought it. I’m glad I did as it performs well, especially for objects requiring low magnification and wide-field views. And this telescope allows for portability and ease of set-up, as compared to my 10-inch solid tube Newtonian, especially on those nights when time is limited.

The optical tube assembly: Purchased from OPT (Ocean Pacific Telescope)

6-inch OTA, f/6 with a 2-inch Crawford style focuser, a 6 x 30 finder (I replaced with an 8 x 50) and it also included tube rings, designed for a narrow-Vixen style dovetail.  An excellent quality telescope in all aspects.

The original dovetail was too short for proper balancing, but I found a unique way to utilize. I flipped it over or upside down which made for a nice carrying handle and for setting up on the mount.

A nice combination as following with a GoTo mount, and with an 80 mm f/5 refractor piggybacked.

 

If you’ve never attempted this faint galaxy cluster, give it a try this October or November. I’ve never been able to see this small group of galaxies from my suburban backyard, with a 10-inch Newtonian.

I’ve seen this galaxy group with a 14.5-inch from a dark-site, but unfortunately without observing notes or a pencil sketch. Unfortunately, on that night it was freezing cold with a 15 mph wind, and my hands were freezing!

I have read articles over the years and heard stories about great telescopes in America for one reason or another, sit idle. Some of these telescopes are classic and very old, but still worthy of great things. 

However, some are relatively new and computer controlled, but for reasons, and some very good reasons are no longer used. The following telescope is in an observatory that was “built in a bad location, dedicated in 1990” on-campus of Gardner-Webb University. However, at the time the observatory was built, this area was actually pretty dark.

I can’t be certain how much this telescope is currently being used, but with so many high intensity lights in close proximity, anything serious or noteworthy would be extremely difficult.

This is a serious research grade telescope with a Paramount GoTo mount and was a donation from Dr. James Herman, MD. The value of the telescope and mount at that time was near ~$75,000.

The observatory is now “unfortunately” surrounded by multiple soccer fields, a baseball field, and multiple tennis courts with a massive number of incredibly very bright LED lighting, so very close.  And many of the athletic fields will often have their stadium lights on, at times well beyond midnight or longer. However, It would have been impossible for anyone at the time the observatory was built to know there would be so much growth in the area, and with eventually so much light pollution.

Unfortunately, the same thing has happened to many observatories throughout the country in the past 50 or so years.  And with the increase and proliferation of high-wattage LED lighting, there are very few dark sites left, especially in the US. But also in the world.

The following telescope sits idle on top of a famous mountain in Southern Nevada, but unfortunately now, the club that owns it has lost access, due to a land sale. This telescope was also a donation by Dr. James Herman, MD. I helped facilitate the donation and logistics of the move.

I’ve suggested to the club officers of the Las Vegas Astronomical Society: The telescope, mount and all salvageable domes and anything else related, should be brought down off the mountain, and put into storage. And then attempting to find a suitable and long-term site.

I was fortunate to be able to play a role in the Mount Potosi Observing Complex in Southern Nevada, facilitating the ~$50,000 telescope donation.

The facility was featured in the February 2016 Astronomy Magazine, the Las Vegas Review Journal, the LA Times, and other publications and media.   

Click on the following link to read the story of this telescope in Astronomy Magazine, which was and still is the largest astronomy related publication in the world.

Note: The road to the top of Mount Potosi is listed as one of the most dangerous roads in Nevada. The mountain is “infamous” due to the Carol Lombard DC-3 plane crash in 1941.

The following Information taken from “Deep-Sky Wonders” by Sue French:

Sweeping 2 1/2º eastward brings us to the cluster NGC 2395. My little refractor at 87x reveals 20 stars loosely scattered across 15′. At 28x, it merely shows a granular-looking patch with two faint stars, but something remarkable happens when I add an oxygen III filter. Although completely invisible before, Abell 21, the Medusa Nebula, joins the scene 1/2º southeast of the cluster! I can see it with direct vision, but it shows up better with averted vision. This unusual planetary nebula is about 8′ across, dented in its northwest side, and brightest toward the northeast and southwest. With my 10-inch scope at 68x, I prefer viewing Abell 21 with a narrowband nebula filter (rather than the oxygen III filter) which shows this large, impressive detailed planetary to be very uneven in brightness.

The Medusa Nebula, (Abell 21, PK 205+14 1, PN G205.1+14.2) 

Planetary Nebula in Gemini

Sharing Observations and Bringing Amateur Astronomers Together

Introduction:

This month’s target:

Abell 21 was discovered during the course of the Yerkes-McDonald survey of  symmetric galactic nebulae. The ensuing catalog was published by Hugh M. Johnson in the May 1955 issue of the Astrophysical Journal, in which it was given the designation YM 29. https://ui.adsabs.harvard.edu/#abs/1955ApJ…121..604J/abstract

The nebula was independently discovered by George O. Abell among globular clusters and planetary nebulae newly found on the National Geographic Society-Palomar Observatory Sky Survey. His paper was published in the August 1955 issue of the Publications of the Astronomical Society of the Pacific, which listed 13 globular clusters and 37 planetary nebulae.

Although the nebula is number 16 in Abell’s list of planetaries, it’s now commonly known as Abell 21. His well-known, updated list of  86 planetary nebulae was published in the Astrophysical Journal  in 1966, and since the nebulae are given in order of right ascension their numbers were changed accordingly.

In his 1961 “A Description of Fifty Planetary Nebulae”  https://ui.adsabs.harvard.edu/#abs/1961AZh….38…75V/abstract, B. A.Vorontsov-Vel’Yaminov, credits the name Medusa Nebula to a 1961 entry in Astronomicheskij Tsirkulyar No.221 (1960), which unfortunately or mercifully, depending on your point of view, I do not have access to.

Abell 21 also known as the Medusa Nebula:  

After spending four nights and ten hours, with two different telescopes, and multiple eyepieces and filters:  I was finally able to “visually” see the Medusa Nebula.  For me…the euphoria of seeing an extremely faint deep-sky object after many nights and hours, can “or might be similar” to something physical, such as running a marathon, which I’ve never done, but I have competed in bicycle races.  

To be able to locate and “visually” see the Medusa Nebula, a very dark sky is most desirable, but which is something I don’t have from my suburban backyard. My best NELM seldom exceeds 5.0-5.2 on a superb winter night. But I’ve always tried to make-do, and thus far, been successful in seeing all of the challenge objects for the past almost 14 years, and now exceeds more than 200 deep-sky objects.  

The Medusa Nebula is the most difficult (visual) object featured to-date in the Observer’s Challenge report for the past almost fourteen years.  This might be proof that a dark site with a 6.0-7.0 NELM is not necessary to enjoy the wonders of the night sky. 

The Medusa Nebula:   

Easy for the imager, but extremely difficult for the “purist” back yard amateur astronomer, using an eyepiece, an O-III or UHC filters, a pencil, note and sketch pad.  

Amateur astronomy can be anything the amateur wants it to be.  But for me, I want it be “not too distant” from the nights, taking out a 60mm refractor, in what I called the “weedy-field” beside my childhood home.  I wanted to see some of those fabulous spiral galaxies (and in color) that I’d seen in my 6th grade science book.  Of course I never did, but without any support or guidance, I learned what was possible.  

I’ve never been disappointed in those very faint objects that are barely visible in the eyepiece, and requires hours or nights to finally see, but somehow “for me” those are my favorite.  Where in the solitude of the night, I might whisper to myself:  THAT’S IT !  

For those few that choose to carefully, and with patience, observe and sketch a deep-sky object, also supplementing with copious notes, they will never forget what that object looks like, and with instant recall. 

After 50 years of observing, I’m so glad I never lost my EP, my pencil, or my sketchpad, as I never had any desire to become an imager.  I also have a library with hundreds and hundreds of “one of a kind” pencil sketches, to review, and for future reference.   

If you’ve never attempted to make a pencil sketch, with supporting notes, you should consider.  And we need to keep the ancient art of visual observing and “pencil sketching” alive.  A skill or facet of amateur astronomy that fewer and fewer seem to be interested in these days.

After all, this was the original reason or concept for the founding of the Observer’s Challenge back in 2009.     Roger Ivester
