Orion CT80 refractor first light review

In this video, I show how I put the Orion CT80 refractor telescope to the test with not so good skies. Making this video was so cold, temperatures were dropping to 1*F and my mount could not slew to park after imaging Orion and Andromeda. I imaged Andromeda through thin sheets of high clouds and Orion through tree branches. Still, the Orion CT80 pulled the lights of the faint deep sky objects. The Orion CT80 is a very high contrast refractor telescope, a black hole!

NOTE: CT80 I did not need tube extender when I used my DSLR & guide camera. However, I did need tube extender for Orion ST80 when using DSLR & guide camera.

Great for entry level beginners. I am very impressed and tempted to buy another one before the prices go up from $93.49. This makes a good buy even for the package deal with guider rings, dove rails, star shoot autoguider under $400 and all you need is a steady 30lbs mount support and you can produce great light images from Monochrome / SSAG and from your DSLR camera.

I give the Orion CT80 8 of 10, the only thing I feel picky about is the very lightweight 1.25 focuser. At the time of creating this video, I am not sure if there a 2-inch focuser upgrade from GSO. CT80 telescope tube and lens are very well constructed with two light baffles to block out the reflecting lights. As for the lens, I don’t know what type but its damn good for guiding and astroimaging with my DSLR camera without needing the Orion tube extender.


Note: Yes, I still like to manual focus, its the only sense of manual labor being an astronomer as the early frontiers who explored the heavens like Mr. Issac Newton, Mr. William Herschel, and Charles Messier.

Great imaging by that refractor, but Isn’t it time that you fix remote control so you can sit inside in comfort and do imaging!

Chris Fleming says:

Love your work man. A touchy focuser can be a pain and I can see where a 2in focuser would be a good up grade.

Karim Amini says:

I have the same setup and i am look8ng for a 2″ focuser for my ct80 any recommendations?

Netty Voyager says:

was this just a mad experiment lol

Garnett Leary says:

Excellent work with such a meager and costless refractor. A plus for Orions product line. A beginner will do well to spend most of their budget on a good mount and buy this as a temporary primary that easily becomes their future guide scope.
