Product Description
Cstar Optic's new Dual Size Erect Image Lens changes your Telescope into a Spotting Scope. Most Telescopes give an up-side-down and reversed image which is acceptable for night sky viewing, but very inconvenient for day-time land viewing. Cstar's new Erect Image Lens corrects the up-side-down image to be right-side-up and correct from left to right just like you see with your own eyes but just at a higher power. Cstar Solves the up-side-down, reversed telescope image problem by providing a new erect image lens which is adaptable to telescopes which take both .965 inch eye-pieces or 1.25 inch eye-pieces. This is a great accessory for your Cstar telescope or to put on most other different brands of telescopes. The dual size capability allows you to use either .965 inch or 1.25 inch size eye-pieces. Moreover, you can now turn your Telescope into a Spotting Scope and Telescope All in 1 and use it for all occasions.... More >>
Cstar EA-125D Dual-size Telescope Erect Image Lens
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).
