The Southern Cross by Commercial Airlines Pilot: James Yeager

March 29, 2021

Jim Yeager has always allowed me to use any of his aerial photos, which over the years have included, a beautiful photo of the Barringer Crater in New Mexico, covered with snow, and the Mount Potosi Observing Complex in SW Nevada. Both of which I’ve used in previous blog articles and other.

I really like the following image, as I’ve never seen the Southern Cross.

Jim’s notes and photo:

Here is somewhat of clear picture taken with an iPhone using a 3 second exposure on a descent out of 41,000 feet about 100 miles north of Lima, Peru.

You can see Alpha and Beta Centauri pointing to the Southern Cross.

The residual cockpit lights, moonlight behind us, and the haze of high altitude cirrus kept us from seeing the Magellanic Clouds.

The Deer Lick Galaxy Group and Deerlick Gap Overlook Near Little Switzerland, North Carolina

October 6, 2020

My objective is to complete a personal goal of seeing and sketching galaxies (NGC 7335, 7336 and 7340) known as “The Deer Lick Galaxy Group.” The three galaxies were given this name by Tom Lorenzin, based on an incredible night of transparency and seeing from the Deerlick Gap Overlook on the Blue Ridge Parkway in the early 1980’s.

But would this galaxy group be possible from my suburban backyard (Bortle 6.5) and with a 10-inch Newtonian?  

Tuesday, November 26th 2024: At 7:00 PM, the sky was clear, but with very poor transparency. After an hour of observing the Deer Lick Group location, I was finally able to see or glimpse NGC 7335, which is the brightest of the three galaxies. However, I could only see this galaxy intermittently and appearing as an elongated blur.

I used my 10-inch Newtonian with a magnification of 208x, and despite all of my imagination, I could not see galaxies NGC 7336 or 7340.

A pleasant surprise: I was able to see Stephen’s Quintet, which is a very faint cluster of five tiny galaxies. I could only see a faint glow or brightening in the location, which would not have even been possible without the use of a GoTo equatorial mount. It’s amazing what we can see, when we know the deep-sky object is in the center of the eyepiece field.

Friday, September 29th 2024 observation notes: Transparency was excellent, as well as seeing. The Andromeda galaxy was incredibly bright and easy to see without optical aid and with direct vision. The NELM was about 5.0 or possibly a bit better, especially in the area of the Deer Lick Group.

Again, I used my 10-inch f/4.5 Newtonian for the Deer Lick Galaxy Group and Stephen’s Quintet. I increased the magnification to 291x, using an 11mm EP and a 2.8x UO Klee Barlow.

After an hour of careful observing, I could only see galaxy NGC 7335, with averted vision. The galaxy appeared very faint, not constant, elongated with no center brightness. I really think I was seeing galaxies NGC 7336 and NGC 7340, but could not confirm, or at least not definitively. (?)

Summary and conclusion: I could not see all three of the Deer Lick Group from my backyard with a 10-inch Newtonian.

Now to Stephen’s Quintet: With improved sky conditions versus my previous observation and with increased magnification (291x) I could see a very soft glow or brightening. No individual galaxies could be identified or seen.

Original article from the Astronomical League’s Reflector magazine, as following:

While driving through Little Switzerland, North Carolina, we stopped at the Deerlick Gap Overlook, which is just off the Blue Ridge Parkway. I’ve always considered this to be a very famous location for both amateur astronomers and professionals alike.

The overlook became the namesake for faint galaxies NGC 7335, 7336 and 7340 in Pegasus, which has become known as the Deer Lick Group. It had nothing to do with the appearance of the galaxies, but from the location where they were observed from.

Tom Lorenzin, author of “1000+ The Amateur Astronomer’s Field Guide to Deep-Sky Observing” was observing from the Deerlick Overlook one incredibly transparent night in October, 1983. He was able to get an extraordinary view of the faint triangle of galaxies. The name stuck, and is now known by many as the Deer Lick Group.

Note: Tom Lorenzin passed away from a heart attack on Aug. 23, 2014 in Winston Salem, at the age of 67. I have known Tom for many years, receiving advice on both visual observing targets and pencil sketching.

Unfortunately, I’ve never been able to see the Deer Lick Group from my 4.8-5.0 NELM suburban backyard, using my 10-inch f/4.5 equatorial Newtonian. However, it’s my goal this year to attempt this trio of galaxies from a dark-site, and if I’m successful, a thirty year goal will be achieved.

I have observed the three galaxies that Lorenzin list as following, with a friends 14.5-inch Newtonian from a semi-dark-site, but I didn’t make any notes, and without a sketch.

So my goal now, is to attempt the three galaxies (NGC 7335,6,40) from my suburban backyard, using my 10-inch Newtonian, during October and November 2024. I’ll also attempt “Stephen’s Quintet.”

The following are Tom’s Lorenzin’s descriptive notes from “1000+” based on his October 1983 observing session from the Deerlick Overlook.

The Questar 3.5-Inch Maksutov Telescope Story: Sadly The Company Closed Its Doors On May 4th 2026

April 25, 2020

Questar was founded in 1950 by Lawrence Braymer, who set up Questar to develop and market Maksutov telescopes and other optical devices for the consumer, industrial, and government customers. The Questar Standard telescope has been in production since 1954.

Questar closed its doors for business on May 4 2026 and the three long-time employees were terminated. Very sad!

The following are some photographs of a friends 3.5-inch Duplex.  

DSCF5015

DSCF5012

   

     During the early 50’s, Cave Optical in Long Beach, California, manufactured the 3.5-inch mirrors.

    Questar graced the back of the front cover of “Sky & Telescope Magazine” for decades!

 

A challenge to Questar?   

     In 1996, Meade Instruments Corporation, introduced the Meade ETX 90mm astro.  This telescope was designed to be an economy Questar, mostly constructed of plastic, but with all the emphasis on the optics.   

At that time, Meade was manufacturing the ETX, and all their higher-end telescopes in Irvine, California.  This included all facets of manufacturing of their many models of Schmidt-Cassegrains, apochromatic refractors and even a 7-inch Maksutov.

     I purchased an ETX 90 the following year (1997) for use as a very portable telescope, to observe deep-sky objects within its grasp.  It served that purpose well.  The telescope had very good optics and would easily exceed “Dawes’ Limit” with good to excellent seeing. 

     Dawes Limit:  4.56/A (A is aperture in inches) for two equal stars of about 6th magnitude.    

     However, when considering fit, finish, cosmetics and ease of use, the ETX cannot compare to the “much more” expensive and precision Questar.  

Full Cut-Off Lighting Fixtures In Matthews, NC: And The Health Hazards Of Light Pollution

March 7, 2020

     Since late summer 2019, my wife and I have had regular business in Matthews, North Carolina, which is a town on the outskirts of Charlotte.  Our Dachshund needed eye surgery, and we take her for regular visits to the Animal Eye Clinic even to this day. (July 2025)   

     Matthews has some excellent and very attractive, full cut-off lighting fixtures.  Lighting should be “fully-shielded” and directed downward to avoid glare and excessive light pollution, as the following photos show.  However, I can’t be for sure of the temperature….hopefully 3,000k or less?  

     No one wants, or should want a bright “unnatural” daytime appearing light, which is that of a 4,000k LED light.  Unfortunately, most all of the new LED lights installed these days are 4,000k or even brighter, which is damaging to human health, wildlife and the natural world.  Unfortunately this light has now become the standard for lighting not only cities, but also for rural and even quiet residential streets. 

     Back to the lighting in Matthews:  Many of the lights have back-shields which eliminate unnecessary light shining into house windows.  This is a great feature.  Proper outdoor lighting should direct light where it’s needed only, downward and with a shield to avoid excess glare.     

     The lights in Matthews, which I’m discussing are in a “seemingly” newer business and residential area.  An example below:   

IMG_1418

      Currently, the trend is to light residential areas and sidewalks in cities are the “short pole” colonial style fixture with 360º of 100 watt and 4,000k LED’s.

     No, I’m not suggesting that lighting is bad, but lighting should be of “intelligent” design, and used only where necessary.   And that would be using lighting of an “acceptable” wattage and with a temperature of (3,000k or less) and with “full shielding” to prevent glare and unnecessary and “excessive” light pollution!   You may try, but seems that few cities are willing to go less than 3,000K for city streets.  

     High-intensity LED lighting and all other “excessive” light pollution is proven to damage or injure wildlife, insects, and also increases the risk of cancer (especially) hormonal cancer(s) in both men and women, being prostate and breast cancer.  

Exposure to Artificial Light at Night Can Harm Your Health!

     Humans evolved to the rhythms of the natural light-dark cycle of day and night. The spread of artificial lighting means most of us no longer experience truly dark nights.

     Research suggests that artificial light at night can negatively affect human health, increasing risks for obesity, depression, sleep disorders, diabetes, breast cancer, and more.

     Like most life on Earth, humans adhere to a circadian rhythm — our biological clock — a sleep-wake pattern governed by the day-night cycle.  Artificial light at night can disrupt that cycle.

     Our bodies produce the hormone melatonin in response to circadian rhythm.  Melatonin helps keep us healthy.  It has antioxidant properties, induces sleep, boosts the immune system, lowers cholesterol, and helps the functioning of the thyroid, pancreas, ovaries, testes, and adrenal glands. Nighttime exposure to artificial light suppresses melatonin production.

     An expressed concern about exposure to blue light from outdoor lighting and recommends shielding all light fixtures and only using lighting with 2700K color temperature and below.   

Some more excellent examples of proper lighting fixtures….

Building a Hot Rod in November 1964: The Beatles Came to America in February of That Year, Cassius Clay Wins the Heavy-Weight Boxing Championship Over Sonny Liston. And I was Eleven Years Old…

January 15, 2020

Date:  November 1964  

     My five older brothers built something similar or akin to what might be called a “Rat Rod” today.  The origin was a 1951 Studebaker…using the frame, which had been shortened by three feet, the original engine and transmission.  

       In the following photos are my brother Jimmy, who was driving, I’m in the middle with the “cool” cowboy hat, and my brother, Phillip.

     My older brothers, Richard, Jimmy, Ronny, Donnie and Phillip, worked on fabricating “The Bug” as it was called.   I was a bit too young, and mostly just enjoyed watching.  Sometimes I would assist by handing them wrenches or anything else they might need.   

     Improvements were made over the next year with the installation of a mid-50’s Chrysler Hemi engine, which had much more horsepower than the Studebaker.     

     The sad looking tires, especially the front white-walls would eventually be changed out with some better looking wheels.  Additions would also be made to the body, however, still constructed of wood panels.  With a larger budget, many improvements could have been made, but….

     My brother, Donnie, being in high school drove the school bus in the background, which was an early 1950’s model Chevrolet.  

An astronomical telescope purchase in 1963:    

     It was my brother Jimmy, who had already purchased (at the time of the photo) a 60mm f/15 equatorially mounted refractor from Sears, at a cost of $100.  This would be the equivalent of $835 in 2019.  An expensive telescope for sure.

     Two years later, I would begin using this telescope to observe deep-sky objects (galaxies, nebulae and star clusters) and a lifelong interest in astronomy would follow, even to this day.

 Improved budget, greater skills and abilities, my brother Phillip would become a race car and engine builder.  He would also go on to win an incredible 164 drag racing events. with multiple drag cars.

Christmas Day 2019: Bicycle Ride

December 26, 2019

     Cloudy skies and rain have prevailed for the past few days, but what a nice day it was on Christmas Day to get outside.  While relaxing shortly after lunch, I received a message from Mike Ribadeneyra, wanting to go for a bicycle ride.  I was actually thinking about a nap, but as a cyclist, when someone offers an opportunity to ride, the guilt can be a bit overwhelming should I decline…and especially for NO good reason. 

     So, after answering the message, I got up and began to get dressed and checked my bike.  It might not be fun preparing to ride, especially when it’s cold outside, being relaxed as I was finishing a good cup of coffee.  However, it’s a great feeling of accomplishment when the ride is complete and riding back into my driveway.  And this is especially true on Christmas Day when my wife and dachshund are anxiously waiting my return!! 

     When headed home, we stopped to visit “Albert” the donkey who loves to see us ride by, behind his pasture fence.  It’s always great to hear him running…fast as he can, from the bottom of the pasture with his collar bell jingling.    

     Albert loves for me to bring him an apple, but it has to be quartered.  He will chew each piece individually.  If a piece falls on the ground, he won’t eat it until I pick it up and offer it to him again.  Albert is a bit finicky, but loves the attention…and especially an apple.

Albert is glad to see both Mike and I.

Sand Dunes In The Northeastern Corner Of South Carolina, 50 Miles From The Atlantic Ocean, Swamps, With Virtually No Light Pollution

August 14, 2018

While visiting our family in Mullins, South Carolina over the past few years, we have enjoyed finding some very interesting things. 

Only a few miles outside the city limits, there are country roads, agriculture fields, and no houses or lights for miles and miles, and virtually no light pollution.        

The next morning….Tuesday August 14th 2018.  

When driving in a secluded area, via unfamiliar country roads, you never know what you may find:   

While riding around with my oldest grandson, John-Winston, who just received his learners permit, and I was sharing my wisdom, on how to be a safe driver.  During our  leisure drive, we found sand dunes, in the middle of a swamp! 

Sand dunes, and a very sandy area….at first resembling snow, all in the middle of a dense forest and surrounded by swamp land.  

There were Bald Cypress trees growing out of the black murky water, Spanish moss hanging from the trees, and who knows, maybe even an alligator or two in that dark water!

Note:  This very remote small sandy area is a protected site.  I took some pictures as following, but somehow missed the eerie swamp.

Cline Observatory Double and Multiple Star List – Compiled By Tom English; Consisting of 25 Doubles and 5 Triples

June 22, 2018

Cline Observatory Double Star List – 25double-5triple 

     Tom English has put together an excellent list of twenty-five doubles and five multiple stars, which at first glance would seem to be compiled for only those new to this facet of amateur astronomy.  However, for those of us who have enjoyed double star observing for decades, we know there is no such thing as a beginners list.  

     Double star lists may be compiled of the most difficult pairs due to their close separations and sometimes with unequal magnitudes, or those with wide separations and beautiful contrasting colors.  It was the latter which coined the name: “The jewels of the night sky.”

     This list contains some beautiful and interesting doubles, all of which can be observed with a small telescope.  

     The famous double star, Epsilon Bootis is probably the most difficult double on the list, which has always required at least a 4-inch refractor for me.  Many observers have reported seeing the companion to Epsilon with a 3-inch aperture.    

     Are you stressed, too tired to take out that big telescope, but would like to enjoy an hour or so of relaxation under the night sky?  So….why not a 60 mm refractor or a 3-inch reflector?   And you don’t have to worry too much about a bright moon or ambient lights as both have little effect on “most” double or multiple stars.     

     Want to become a better double star observer?  I’ve listed a few things as following which have helped me over the years:  

     I’ve never been able to observe through a telescope eyepiece and stand at the same time, much less attempt to separate a very close pair.     

     And for those extremely close and difficult doubles, an eyepatch is necessary for the non-observing eye.  

     It’s important to relax the facial muscles and “absolutely” essential to hold the observing eye very still and on-axis….hence the need to be seated.  

      A good quality astro-chair, as pictured below is a must when observing double stars.

Edmund Scientific Of Days Past: The Company That Inspired So Many To Become Amateur Astronomers

February 21, 2018

Edmund Scientific was the company that really fueled my interest in amateur astronomy.  From their telescopes and accessories to their many beginners books.  My first telescope was an Edmund 4.25-inch f/10 reflector, with an equatorial mount.  Not my first choice, but the best my budget would allow at that time.  Prior to this, I used my older brother’s 60 mm f/15 EQ refractor.  (Photo at the bottom, in an old rented house on a textile mill village, with a street light in the backyard!)

I was just getting started with my first real job, but most all of my money was required for the essentials of life, with little left for a telescope and astronomy equipment. 

My first telescope was an Edmund 4.25-inch Newtonian, which allowed me to see many of the Messier objects. I was living in a highly light polluted area at that time, so finding deep-sky objects with setting circles was like magic. Star-hoping to locate faint objects can be almost impossible with severe light pollution. 

Not only did Edmund Scientific have telescopes and astronomy equipment, but also plenty of resources to learn how to use a telescope. The following books from Edmund taught me so much about amateur astronomy, and I still reference them even to this day…more than 50 years later.

1910322_1_IMG_2476

 

During those early years it was my goal to see the entire Messier catalog, which I would eventually accomplish, and received my Astronomical League award certificate. but would eventually see over 2,000 more deep-sky objects, complete with notes and pencil sketches.  

I’m glad I didn’t quit during those early years, despite all of my obstacles, and regardless of the amount of light pollution, there are always deep-sky objects that can be observed.  So, don’t give up!   

University Optics Closes Doors After 50+ Years

December 3, 2017

I’m a bit late in finding out (January 2018) but University Optics closed its doors in ~June 2017.  I was saddened to hear this.     

I purchased all of the original UO Konig’s over 30 years ago:  A 12mm, 16mm, 24mm in a 1.25-inch format, and a 32mm 2-inch…also a 20mm UO Erfle, and a 2.8x three-element apochromatic Barlow.  I have, or have had many other eyepieces over the years, including Televue, Celestron, Meade and others.  But I still use my Konig’s quite often, even to this day.  As a visual observer, I love eyepieces.  However, my last eyepiece purchase was over ten years ago…an 11mm Explore Scientific 82º AF bought in-person, from the Park’s Optical store in Las Vegas.   

It’s very sad to see a company that supplied mirror making kits, mirror cells, diagonal holders, and many other low profit items, now out of business after more than 50 years.  

University also sold a 6-inch f/8 Newtonian and an 80mm f/5 achromatic refractor in kit forms.  The refractor required both assembly and paint. The Newtonian only required assembly.  The 80mm was an air-spaced achromat which received many excellent reviews.   

University Optic’s will be missed by the amateur astronomy community.  So many great “made in  America” astronomy companies are no more.     

My University Optics eyepiece collection as following, and all still in pristine condition.
