Visual Observing With A 6-inch f/6 Imaging Newtonian And Resolving Pinched Optics
Posted November 17, 2023 by rogerivesterCategories: Uncategorized
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! π
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.

Galaxy IC 10 Cassiopeia: “The Invisible Galaxy” November 2023 Observer’s Challenge Report #178
Posted November 13, 2023 by rogerivesterCategories: Work File Only - Observer's Challenge Reports
Roger Ivester: Observer from North Carolina
Telescope: 10-Inch f/4.5 EQ Newtonian
Sketch Magnification: 142x
FOV: 0.46
NELM: 4.8
So during the months of October and November 2023, three observing sessions and more than six-hours at the eyepiece, I was finally successful in seeing this galaxy.
So by own authority as an amateur astronomer, which is no authority, I’m naming this galaxy: “The Invisible Galaxy.”
A difficult and very faint low-surface brightness galaxy, using my 10-inch Newtonian. After three nights with poor transparency, and more than six-hours of observing I was finally about to make my final sketch, as following.
The first thing to look for is a triangle of three mag. 9 stars, with the galaxy being just to the N.
The galaxy appears as a mere brightening in the sky, but upon careful observing over the three nights, the glow of the galaxy halo became enlarged, and elongated NNW-SSE.
There is an extremely faint, and very subtle brightening in the middle. A faint star is visible near the center and a mag. 13 star is fairly easy to see just to the W.
In the following sketch, note the pair of faint and close double stars in the NW edge of the field.

Historic Building In Boiling Springs: Beginning As General Store Circa 1910, Then As A Post Office In The 1930’s. A New Coffee And Bakery (Sweet Eats) Will Open Thursday September 25th 2025.

Early 50’s: Photo credit Tommy Greene


We visited the coffee shop earlier today (Thursday, September 25th 2025)



Debbie and I thought it would be good (a year or so ago) to document a little history concerning the building, and some information about W.J. Cash from wikipedia: So Read on...

Excerpts and photo as following from Wikipedia: The article is very long, so I tried to take out as much as possible, but leaving what I thought was the most important.
Wilbur Joseph “Jack” Cash (May 2, 1900 β July 1, 1941) was an American journalist known for writing The Mind of the South

Early life and education
Cash, known as “Jack” throughout his life, was born as “Joseph Wilbur Cash” β he later reversed the order of his given names, and normally used only the initials β and grew up in the mill village of Gaffney, South Carolina. He had three brothers and a sister, of whom he was the eldest. He was educated at the local public school until he was 12, when his family moved to Boiling Springs, North Carolina, 14 miles away across the state border β his mother’s home town β so that his father could become a partner with Cash’s maternal grandfather in a general store there.
…..In 1918 and 1919, at his father’s wish, Cash attended Wofford College, a Methodist school, but left because he objected to the school’s narrow provincialism. He then enrolled in Valparaiso University, a Lutheran college in Valparaiso, Indiana, dropping out around Christmas 1919. In 1920, again at his father’s urging, he entered the Baptist school Wake Forest College, despite it being what he considered to be a “preacher college.”[2]
In the summer, he worked at the hosiery mill at which his father was then the superintendent. Cash graduated in 1922 with an A.B., and then attended law school there for a year, before deciding not to pursue a legal career.[2] Cash later declared that he left law school because it “required too much mendacity.”
…..Cash taught English at Georgetown College in Georgetown, Kentucky, and at a high school in North Carolina, before experiencing a nervous collapse. Throughout his life, Cash suffered from manic depression or affective disorder, which manifested itself in breakdowns, periods of depression, fear of sexual impotency, and physical ailments such as not being able to swallow or choking when he spoke. He also suffered from a hyperthyroid condition, occasional alcoholism and excessive smoking. Cash usually referred to his condition as “neurasthenia“.[7]
From 1926 to 1928, Cash held several newspaper jobs: a year in Chicago writing for the now-defunct Chicago Evening Post; several months with The Charlotte News during which he wrote a wistful philosophical column titled “The Moving Row”; and a four-month stint during the fall of 1928 as the chief editor of a small semi-weekly newspaper, the Cleveland (County) Press, in Shelby, North Carolina.
…..Afterwards, Cash moved back into his parents’ house in Boiling Springs β where he lived with his extended family, including his two brothers and their pregnant wives. He contributed to H. L. Mencken‘s The American Mercury magazine, and received encouragement from Mencken. From 1929 to 1935, Cash wrote eight articles about various aspects of the South,[a] including one in October 1929 called “The Mind of the South”, which would become the basis for the later book.[b]
During the period of primary writing on The Mind of the South (1929 to 1937), Cash continued to live with his parents in Boiling Springs.[9] When his contributions to The American Mercury ended after Lawrence Spivak took over ownership of the magazine, Cash supported himself with freelance weekly book reviews to The Charlotte News from 1935 to 1939, for each of which he received a payment of $3, equivalent to about $60-$65 in 2023.
Cash’s seminal article, “The Mind of the South”, was published in The American Mercury in October
In 1932, however, he began to write seriously again, using the unheated back room of the Boiling Springs Post Office, where his aunt was the postmistress.
After Cash had some success at The Charlotte News, he finally had the personal and professional confidence he had previously lacked, and his work there helped him to develop his unique style of writing. He also met and fell in love with Mary Bagley Ross Northrup (later known as Mary Maury), a divorced woman who also wrote for the paper, and who helped him to complete the book through his periods of depression, and his continued focus on events in Europe. During this period, Cash would listen to the news on the radio about the Anschluss with Austria, the invasion of Poland, or the fall of France and would pace around the room, biting his nails, hands, and wrists, leaving marks. He would become so upset that he would leave the house and walk the streets at night.[14]
Finally, on July 27, 1940, the last pages of the manuscript were finished and sent to New York. Five months later, on Christmas Eve, Cash and Northrup were married by a justice of the peace in York, South Carolina.[11][2]
On February 10, 1941, The Mind of the South was published by Knopf. The book, an intuitive socio-historical exploration of Southern culture, received wide critical acclaim at the time and garnered for Cash praise from such sources as Time, The New York Times, The Saturday Review of Literature, and most Southern newspapers of note, although criticism came from the Agrarian group out of Vanderbilt University in Nashville. Cash also received the thanks of Walter White, the director of the NAACP, for the book’s liberalism in regard to race and its exposure of the bigotry of the South.[15] Time said of The Mind of the South “Anything written about the South henceforth must start where [Cash] leaves off.”
Cash and his wife chose Mexico to spend their year on the Fellowship because it was cheap to live there, and they would have to watch every penny; they embarked on their trip to Mexico City on May 30 1941.[2] Cash had been invited by University of Texas president Homer Rainey to provide the main commencement address to the 1941 graduating class on June 2 in Austin, Texas.
While in Mexico City, Cash came under an apparent psychotic delusion. On June 30, he told his wife that he heard Nazi assassins whispering in the next room, plotting to kill him. The next day, when he was calmer, she went to get help. On her return with a correspondent they had met earlier, Cash was not in the room.
Hours later, he was located in another hotel, the Hotel Reforma, where he had hanged himself with his tie from the bathroom door.[17][d] An autopsy failed to find evidence of a brain tumor. Cash’s remains were cremated, and a funeral service was held in the First Baptist Church in Shelby. The ashes were later envaulted in Sunset Cemetery in Shelby.[2]

Seeing Sirius B With A 10-inch f/4.5 Newtonian Using A 5 1/4-Inch Effective Aperture And Also With A 102mm FS Takahashi Refractor
Posted October 31, 2023 by rogerivesterCategories: Roger's Articles
Now is the perfect time “to attempt” Sirius B: It might be easier than you think. (?)

Why an off-axis stop-down mask?
“Often the effects of poor sky stability can be countered to a certain degree. Larger aperture scopes are adversely affected by atmospheric turbulence more than smaller scopes. The cylinder of light of parallel light rays collected by an 8-inch object is subject to a larger cross section of the atmosphere than is that of a 3-inch. The greater the amplitude of of variation in air parcel boundary layers perceived by the system, the more this refractive aberration manifests itself as image wavering. “For certain deep-sky objects (notably double stars) one needs to trade light gathering ability for turbulence reduction. The aperture of the telescope can be reduced by employing a mask over the light gathering end…..” by TL
Tom Lorenzin “1000+ The Amateur Astronomer’s Field Guide to Deep-Sky Observing”
I’ve never tried or attempted to see Sirius B with a Newtonian. I was anxious to give it a try with my 10-inch f/4.5 using an off-axis stop-down mask with an effective aperture of 5.25-inches.
November 2nd 2023:
Beginning at 5:30 AM with a 3rd quarter moon and really bright. I concluded my session at 7:20; approximately 30 minutes before sunrise. I was still able to see Sirius B!
Surprisingly, I could still see the companion just as well at 7:20 AM in very “dim daylight” and still with a fairly bright moon, as when I began almost two hours earlier. This would show and prove that double stars can be enjoyed with a moon and light pollution.
I used a small plastic protractor to help me determine the position angle of Sirius B, and where to look.

My first time seeing Sirius B occurred in 2016, using a 102 mm f/8 FS fluorite Takahashi refractor in March 2016, from Lost Arrow Ranch. My good friend and astronomy associate Don Brooks of many years owns this telescope.
It was actually very easy with this telescope using direct vision. A group of six amateurs took the test.
Using the face of a clock, and all without sharing their perceived position of the companion until everyone had the opportunity to observe. Β When the last person completed their observation, allΒ correctly identified the position of Sirius B. Β
Some were very skilled observers, but a couple or more were not, however, all could easily locate and see the companion.

Roger, thanks so much for the off-axis mask idea….wonderful.
Sirius B:
After several or should say “many” attempts I spotted Sirius B in May 2020, using averted vision. My eyes were tearing, cloth over my head and let Sirius pass through the eyepiece. However, after 45 minutes of struggle, I saw the companion.
To-Date: I have now found and seen the companion, also known as Sirius B several times, but it’s still never an easy. It is important to have a stable and clear sky, and good seeing is “absolutely critical” if you are considering taking on this task.
Interesting; I found if Sirius is in the west and after sunrise, seeing Sirius B is actually easier, which might be surprising to many. Roger Ivester, mentioned the same in his report. Magda
1971 Burns High Class Reunion: Saturday October 11th 2025 At Hanna Park In Shelby, NC. The 2023 Event Is Also Included: Just Keep Scanning Down
Posted October 21, 2023 by rogerivesterCategories: Roger's Articles
1971 class reunion: October 11th 2025: And a great time was had by all! It was a breezy (windy) and really cool Saturday afternoon.
The 2023 event follows 2025….just keeping scanning down.










I missed getting a “face-on” picture of Debbie. How was that possible? So, I thought I’d just share a photo of Debbie and Sophie from May 2025.

Photos of the 2023 Burns High School class reunion are as following: Much appreciation to Charlotte Sinclaire for taking the lead in organizing this fabulous event. Everything was perfect! A memorable class reunion for sure.











In the following photo…Five guys began 1st grade at Polkville in August 1959, and graduated together at Burns. We were the first class at the new school, and went all four years.
However, after the 5th grade, some of us parted ways for three years, some went to Casar and some went to Piedmont…but back together again at the new Burns High School in the fall of 1967.
