Very nice little scope sold under the TS Optics and Tecnosky brands. FPL-53 triplet objective with a built in fixed position doublet corrector that provides a 45mm corrected image circle. No sensor backspacing requirements. As long as it can reach focus the field will be flat. Even has a built in tilt adjuster and CAA. The stars are very good even in the corners of the IMX455 in my Sigma FP-L. Chromatic correction is superb 👌. I have only gotten a few test shots in so far but I'll post some samples when I have some more time. I also took some images of inside, outside, and at focus with a 10 lines/mm Ronchi photographic eyepiece and the results look really nice. I'll post them after I get around to getting them from my camera to the computer.

90mm F5 and 3.2" dual speed focuser compatible with ZWO AEF.

Objective. The reflection is from the quad band filter on the back and the odd pattern is my ceiling.
