Cstar CMOS Digital Color Eyepiece for Telescopes w/Photo and Video Capability Review

My hopes were flying until I purchased this item. I noticed the resolution (0.3 megapixels - that's a "0." in front of the number) and started to worry. That worry was more than justified when I installed the software, hooked up the eye-piece and set up my laptop on a table outside. First I focused on Jupiter and its 4 largest moons using the optical eye-piece that came with my Meade Telestar NGC-60TC telescope. This particular telescope always gives good results with Jupiter and its largest moons as well as Saturn and its rings. Then I replaced the optical eyepiece with the digital eye-piece. Refocusing, very carefully, the best I could do was a blob of light for Jupiter and NO MOONS WHATEVER. I can imagine getting fair results looking at the moon, but for the price one expects a bit more than the moon when your interest is astronomy.

Cstar EA-125D Dual-size Telescope Erect Image Lens Review

Pros: Good (large) clear aperture
Good quality image
Cons: No eyepiece set screw
Telescope end tends to unscrew sometimes (due to .965 adaptation)

I purchased this erect image diagonal for use with a homemade spotting scope and it has not disappointed so far. See comments above. I got over the lack of a set screw by tapping the eyepiece end with a 4/40 tap and inserting a 4/40 thumb screw purchased from Small Parts Inc (also accessible through Amazon).
