60 YEARS
I’ve been at this a long time. Starting from a 4 inch reflector up to 36 inch monsters, I have been hooked on the stars and making telescopes since I was 12 years old. The photo below is me with a 6” reflector that I built in high school. Astronomy and large aperture telescopes are my passion. 39 years ago I started Obsession Telescopes and 3000 big scopes later I’m still at it. In that time, 28 telescope companies have gone out of business. When traveling light years, you deserve to go First Class. Joe in Colorado agrees. He says:
“I just wanted to quickly say, that everyone I talk to and everyone on platforms like YouTube all praise Obsession Telescopes as being the best. I think that it is safe to say that you and your scopes are recognized world wide as being the premier scope to own. What an accomplishment! I have owned my 15 inch now for about 20 years and love it! I feel as if it is becoming a collectors item. Thank you for creating such a great product.”
Thank you,
Joe W Colorado
No need to wait
No need to wait a year for a scope like our competitors. We pre-build them 100 at time so you don’t have to wait to enjoy the views.
Get on the list!
In 2024 we are producing 150 more Ultra Compact telescopes.
We will also produce fifty 15” f/4.0 UCs, fifty 18” f/4.0 UCs, and fifty 22” f/4.0 UCs. Get on the list!
Newly completed 22" UC mirror cells show here.

In 2019 we produced ten 20" f/4 Classic and twenty 22" f/4.2 Ultra Compact telescopes. In 2020/21 we will produce fifty 15” f/4.2 UCs and twenty-five 18” f/4.2 UCs. Get on the list!
Fused quartz
All Classic and Ultra Compact 15”, 18", 20” and 22" Obsessions use fused quartz (also called fused silica) for the primary mirror glass. Fused quartz is glass consisting of silica in non-crystalline form. It differs from traditional glasses in containing no other ingredients, which are typically added to glass to lower the melt temperature. The optical and thermal properties of fused quartz are superior to those of other types of glass due to its purity. Its low coefficient of thermal expansion makes it one of the finest materials for precision mirror substrates. Fused quartz is standard on all our 15”, 18” and 20" scopes, both Ultra Compact and Classic models. Nobody else offers this level of quality.
34 year anniversary
In 1987 I introduced the Classic Obsession 20” at Astrofest. Since then it has been the most imitated large aperture telescope in the world. I am still am obsessed with deep sky astronomy and producing the finest instruments possible. I’ve built over 2,500 Obsession telescopes, wrote the number one selling book on building big Dobs, started the Ultra Compact line of scopes in 2008, and provided nearly all the design innovations that everyone else imitates. Choose from the warm and beauty of the Classic Obsession or the modern Ultra Compact telescope. Either choice is the best instrument available anywhere at any price. An Obsession Telescope will provide you with a lifetime of observing fun.
