Are you looking for images of any particular models such as this one?
In any case, you’ve done an excellent job on the website, very classy.
Looking for instructions for H3T-1 Scope.
very impressive site.
i can look for hours to these impressive “giants-of-the-past”.
At home I’m living with a 2,4″equatorial electrical driven, a 3″ equatorial electrical driven and fully loaded and the 4″ pier-model, weight-driven.
By the way, the Delft University is the “home” of the Polarex-Unitron 9″ (226mm), but sadly not in operation-mode…
But it came here by lucky coincidence.
We have one for sale. I have no idea how much it is worth. I can send detail pictures. It is in 3 wooden boxes. It has one lens.
I remember my High School Science teacher selling me the Unitron 2.4″ alt/azimuth. It had the rotary eyepiece with 5 eyepieces!
I still use this piece of art for moon and Sun observations and photography. Thanks for the website! Oh by the way, the purchase price was $40.00 !!!!
I am glad that the history of these wonderful instruments is being organised and preserved. I had the shock of a lifetime 5 or 6 years ago when a gentleman offered an old telescope to me. When I went to pick it up I discovered it was a model 152 unitron complete with cases and all except for one thing, the scope had a cast aluminum plates for the tripod table but there was no clock drive. It took me several months of digging but, I did find out all I could about the company. In the states eventually they were sold under the name unitron.In Europe, it was sold under the name polarex and from what information I found,it was sold under the Japanese telescope company. During the war seiko made optics for the war effort , after the war he developed the telescopes. The fittings that are on the scopes varied from year to year depending on what was available at the time because of material shortages such as the bakelite supports. also the setting circles Ive seem them with silver on black black with silver and black with white scales. I consider myself lucky to own a model 152(restored) and a complete model 114 with unihex and all cases.
a number of years ago I went to the Unitron office in Bohemia Long Island to purchase an altazimuth mount for a televue refractor I had purchased. In the showroom was a Unitron 4inch equatorial completely made of brass. The manager said it was missing an objective lens. I enquired if it was for sale and he said for $2000.00 I could have it. Sadly that was way out of my price range. Have you heard of this telescope?
Hello, you can add my name to the collectors list, as I since early 1980-s has been owner of a 4-inch equatorial mounted Unitron refractor. It is used now and then and still looks like new. Not sure of model, but seems like a 152. I like this web-site with all the information. I have the Sky an Telescope magazine with the story of Sky High Observatory in Norway.
My name is Chris Paynich.I purchased a Model 152 in March of
1976. I have used this scope for 40 years now and have enjoyed it every year.I have been looking for information on the weighted clock drives,mfr and other info.Not much is available, many articles.I wanted to find more info on these instruments.I would appreciate any info anyone could provide.I am looking for an electric motor drive also. Thankyou,Chris
Thanks again to you and Chuck for your visit!
This is by far the best site I have seen on Unitron Telescopes.Thank you for that.
I have a model 160. No rust no oxidation but some chips and scratches.If you don’t mind me asking are the black and the white paints powder coated? And could they be touched-up somehow? I don’t know if this site is here for this kind of help but if it is Thank you. If not thanks for all your hard work. Larry
Information provided by one of the better known Unitron restorers: “For the black I spray a little of the Rustoleum Satin Black #7777 in a cup and touch up with a small modeler’s brush. I do the same for white using the Rustoleum Appliance Epoxy.”
Hello, I’m writing to you from Minas, in Uruguay, South America. I’m an Astronomy teacher from a local public high school, where we have an educational Astronomy Observatory, with an early 1960’s 4″ Unitron refractor. Luckely we and our colleagues have been able to preserve it, but we are still missing some accessories, like the motor drive. Although the original pier has the space to put a weight driven clock, our guess is that the telescope never had one. So, we are trying to get a motor drive, in order to have tracking for our observations. Most of our activities are educational, so we usually have many observers, students and teachers mostly.
We would like to know if you could guide us in order to get a motor drive. I don’t think we will be able to acquire an original Unitron (although we wish…), but at least a diagram for a motor drive that would fit and work with our Unitron (we use 220V, 50Hz).
Thanks a lot in advance for the information you could send us. Congratulations for this great website, and we promise to send you more information about our activities and our telescope soon.
Greetings from Uruguay,
healo dave my name is martin i live in australia in a state called queensland i am very interested in unitron telescopes and i am wanting please to know where you can buy them brand new in america or and here in australia.please tell me are they still making them new i have read that a lot of people are trying to keep them in operation.please tell me where in america the name of the telescope shops where i can buy them brabd new thank you from your client martin evans.please email me on email@example.com
Hi, my name is Jordan Hargis and I am a Student Director of the Observatory at Indiana State University, and we have a Unitron pier mounted telescope that is in need of some repairs. The scope was donated to us I think back in the 60s or 70s along with an observatory dome, but here at ISU we do not have an astronomy program so it has basically just sat up on the roof since it was put in. It has been covered and kept mostly dry, I do not believe it is in terrible shape just needs some tlc. I also can not find a model name or number, so I guess my question is if someone could help me identify which one it is. I have recently been given the ok to buy some parts for it(if they are even avalible) to get it back in working order and put some live back into astronomy here at Indiana State University! So if anyone could please lend a hand it would be much appreciated! Thank you, and sorry for the novel of a comment!
I have a unitron 70mm spotting scope with 4 eye pieces, i cant seem to find any information about it, can you help?
Hi, I spoke with Ron Lewis and his group of astronomers at the Green Mountain Alliance of Amateur Astronomers for a little local news story I am writing about restoring the Unitron telescope at Castleton University. They told me about your project and your visit to see the campus observatory last year. They also directed me to your website for details. May I use quotes from you from the website where you talk about the Vermont telescope? Fascinating story and your project is noble for rescuing these magnificent instruments!
Certainly, Louis. Would appreciate a copy of your story. Thanks
Today a friend gave me what seems to be an old Polarex refractor. I think it will turn out to be Model 114 (D60mm Fl 900). The outer edge of the objective lens has a piece chipped off. I am really only a beginning amateur astronomer and other than what appear to be normal eyepieces I am not certain of what all the parts I have are used for. One cap-like part with a side-mounted screw may be for use with the sun.
Can good parts for this scope still be found? I should add that presently I don’t have a tripod that would attach to what seems like an alt-azimuth base. There are no declination or right ascension markings on the metal base that I have. I do have the storage box and it would seem that I have, at least, correctly identified the telescope.
its me again.
Sorry, i have forgotten to say that it is a Unitron 4 inch / Zoll / 102mm Refractor.
I need some information to open the cell,the spacers/thickness and are they glued on the lens and how to make spares.
Hope all goes well with you. I was reading your 6″ inch Unitron intro when I noticed an image of the Mercury transit by the Hans Arber using a 6″ Unitron in the Philippines. Note that there is another published photo by Hans Arber of the sunspot maximum of Dec 25, 1957 in “Outer Space Photography for the Amateur” Amphoto, 2nd Edition, 1963, page 66 authored by Henry E. Paul. Just in case you missed it!
I am glad to say that I own a Unitron 132C, a 4″ compact refractor, that I purchased in 1980 from the Polaris Telescope Shop in Dearborn, Mi. It is in mint condition, not a nick or a scratch, with all accessories except the motor drive and sun glass filter.
Thanks for letting us know! Would appreciate some photos to post on the website.
Please contact me at firstname.lastname@example.org I want to find out more about the Polaris Telescope Shop.

Just purchased a Unitron 131-c (6-27-17) from an antique shop for $50. The objective lense is c-553. It’s not the original tripod, no spotting scope and only has the 9mm lense. I’m still very excited with the find, but it will need some work to clean it up.
I have a Polarex.1, which is a 42mm X 700mm and I’ve looked on the web pretty extensively and cannot find any info on it.
I have a model 140 , 3” Unitron telescope that was my grandfathers. I think it must be 60 years old . Along the way things have been lost I’m assuming. I was curious if it was worth anything. Still use it on occasion with my grandson. Was wanting to upgrade. Any help would be great. Wish I could post a picture but can’t do it here.
More info is needed on the Brandon-AP-Unitron. They made 2 of the “4 inch” models, a 94mm and a 92mm. Also, the later units had lighter accessories because the original Unitron focusers were heavy. I had three of these scopes around then.
(Stop me if you’ve heard this before!) I recently purchased a Unitron 152 and am trying to find out when it was made… It has block lettering but no diameter or focal length markings on the focuser. I can’t seem to find this anywhere!
I have a green 102mm UNITRON lens #5041 that I’m thinking of selling.
Cheers Dave (australia)
Hi Dave, It was great chatting with you at NEAF in April. Your Classic Telescope display was just wonderful and sure brought back memories of drooling over the Unitron ads in S&T. Your web site is just fantastic and I have spent hours looking through it. Thanks for the fun.
just got SUPER-UNIHEX
MY QUESTION IS, HOW MANNY SUPER-UNIHEX DIT THEY MAKE.
AND JUST BUY !!!! POLAREX-132F
LOOKING FORWARD TO YOUR MAIL
GREETINGS FROM KIWI
Hi I have just bought a Unitron 80mm spotting scope with full height tripod, it still had the original receipt in the box. Just wondering if anyone would know where I could get a manual.
