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.
