The 29-Inch f/4.5 Don Brooks Telescope Which Is One Of The Largest Privately Owned Telescopes In The Region

February 20, 2026

An observing event was held last night (February 19th 2026) on the campus of Gardner-Webb University in Boiling Springs, NC, featuring a custom made 29-inch telescope by Don Brooks. Don has been active in amateur astronomy for many years, and is currently the President of the Cleveland County Astronomical Society.

It should also be noted: Longtime CCAS member, Steve Davis also attended the event last night. Steve works at the “Bare Dark Sky Observatory at Mayland Earth to Sky Park” and is an operator of the 34-inch telescope. The facility is located in Burnsville, NC and the 34-inch telescope is one of the largest public telescopes in the southeastern US.

I’ve been friends with both Don and Steve for more than 30 years.

The telescope:

It has a 29-inch mirror which was produced by Coulter Optics in California during the 80’s. No one seems to know “definitively” how many 29-inch mirrors were produced. Don is aware of “possibly” eight to ten. However, I communicated with an amateur on (February 20th 2026) living in Minnesota who has one in storage, which would add to the count.

Don built everything (other than the mirror and the focuser) which was an extraordinary task. A mirror this size has incredible weight and the mirror cell must be built strong enough to properly hold and secure without causing stress to the mirror. Building only the mirror cell is an engineering feat in itself.

I can’t properly convey just how difficult building a telescope this size would be, and the mechanical skills required.

The mirror cell designed and build by Don, is both beautiful and strong with 27-points of support.

After 34 Years: Time For Another Amateur To Own This Large Newtonian

February 14, 2026

In about 1991, I began looking for something larger than my 4.5-inch reflector which I was using at that time. The Meade Deep-Space series Newtonian’s consisted of two telescopes: A 10-inch and 16-inch f/4.5 with equatorial mounts.

This was at a time when Meade was building their serious Newtonian’s in their Costa Mesa, facility, which included grinding and polishing mirrors.  All of the hardware, bolts and Allen heads on these telescopes and mounts are SAE, not metric, which goes back to days past.

Astronomy Magazine tested a 10-inch DS-10A (The 10A was an updated version with a 2-inch focuser, setting circles, and RA drive) with the magazine giving the test mirror a rating of a B+.  

So, in February 1992, I purchased the 10-inch from Pauli’s Wholesale Optics, in Danbury Connecticut. It was Fred (the owner of Pauli’s) that recommended this telescope. It was a good decision as I have been successful in making more than 1,500 deep-sky pencil sketches and thousands of observing notes.

The low pedestal mount is ideal for use with an astro-chair, when making observing notes and pencil sketches at the eyepiece. As for me, it’s impossible to observe and sketch while standing.

The new owner of this fabulous telescope which served me well for 34 years. I spent over 2,000 hours under a night sky and thousands of pencil sketches of deep-sky objects, and the scope is still in pristine condition. The telescope was always stored inside and in a padded zip-up bag.

It was a sad day, but a happy day as the “perfect amateur” came to take this scope. I’m sure it will allow him at least 34 years of deep-sky observing also.

The first night out (Friday February 13th 2026) the new owner has already imaged the Orion Nebula, Jupiter and other deep-sky objects. This is actually an imaging telescope, with the mirror moved up for full illumination, and with an RA drive, which I never used. An extender tube is required for visual observing.

The new owner is a professional high-speed video camera expert for industrial applications and also an experienced amateur astronomer.

Yes….the very first images and on the very first night out! I’d say pretty impressive!

T Corona Borealis: February 2026 Still Waiting And Watching

February 7, 2026

The first observed outburst of T Corona Borealis occurred on the night of May 12th 1866, and the star when noticed was about the brightness as Alpha Coronae, magnitude 2.2. (Source: Burnham’s Celestial Handbook; Volume Two; Page 708)

My “latest” cell photos as following: I hope to keep this effort up, but at the moment…only if I wake up in the early AM. It will be quite a while before Corona Borealis becomes an evening constellation. For those with an interest in keeping up with T, it is in excellent sky position at about 3:00 AM and later.

Following photos: I’ll post the most current or recent first, and drop off the last…maintaining about ten photos or nights for review via this post.

Where is T located in the constellation? The following photo is from wikisky.org and has T marked with an X and inside the box.

Open Cluster IC 4665 In Ophiuchus: Deep-Sky Wonders

February 5, 2026

From “Deep-Sky Wonders” Walter Scott Houston: selections and commentary by Stephen James O’Meara:   

“Many years ago Glen Chaple, Jr., of Townsend, Massachusetts, “discovered” a deep-sky object in Ophiuchus; he found about two dozen stars forming a group which could be glimpsed with the naked eye.  He likened the cluster to the Praesepe in Cancer, but was not plotted on his copy of “Norton’s Star Atlas.” The object does, however, have a name.  It is IC 4665 and is listed in the “Index Catalogue” to the NGC. In those days of stargazing, serious deep-sky observers soon learned that no single atlas can suit all their needs. Today, of course, IC 4665 is plotted on most modern star charts.” WSH

Now from Sue French “Deep-Sky Wonders” A Tour of the Universe With Sky & Telescope’s Sue French as following:

“The splashy open cluster IC 4665 is barely within the boundary of the Milky Way on the atlas. It’s easy to spot 1.3º north-northest of Beta Ophiuchi, which shares the field of view through binoculars or a finderscope. In my 15×45 image-stabilized binoculars, the cluster’s prominent core spans more sky than the full Moon, and loosely scattered outliers to 70′. Half its 40 stars outline a rough circlet with one star at its center and a stem that leads westward to a slightly wavy line tipped north-northwest. To me, it looks like a simplistic drawing of a flower springing up from a gently undulating patch of the ground. Finish amateur Jaakko Saloranta comes away with a different impression. Through his 80mm refractor, he sees the group as the Fish Spear of Poseidon. ” Sue French
