STARBASE ORTHOSCOPIC EYEPIECE

I was really impressed by how sharp the view stays across the whole field — the low distortion claim is no joke. The 45-degree apparent field is plenty wide for my lunar observing sessions, and it's comfortable to look through for long periods.

The eye relief on this 20mm ortho is spot-on for my comfort, even with glasses on. Stars are pin-sharp right across the field, with no noticeable distortion in the center.

The 20mm focal length gives me crisp, steady views of Jupiter’s bands without any color fringing. Eye relief is tight but manageable with my glasses, and the 45-degree field feels perfectly wide for lunar observing.
