Good mirror and compression fittings fits well for 2" eyepieces

This is a beefy, solidly constructed diagonal. Smooth action for the clicklock and compression rings hold eyepieces well. Interior has a matte black finish and some baffling design. Mirror has a beautiful finish and light comes through very well.The only issue I have is with some low power wide field eyepieces, my scope does not have enough inward travel to get images in focus. Planetary and mid-power wide field eyepieces all work great.

WOW, a SVBONY product that is equal to the name brand products! I wanted a "90 Degree Diagonal Mirror 99% Reflective Dielectric Coating" and WHY YOU SHOULD BUY is, very good quality and the SPECIAL LOCKING feature, closes feature to Baader twist lock. But that is known to not center the EP in the dead center as it uses an open side ring that closes when tightening it, so it locks really from 1 side. Very good but not perfect.Now the 2-SVBONY 2" & 1.25" Diagonal with 99% Dielectric" has 3 ribs that all tighten as 1. Maybe not as lock tight as the Baader but for the price like these!When on sale hard to beat! Just wished it had a bigger opening but for visual a MUST BUY!!

Diagonal works fine, but was I highly suspicious of it being Erect Image (which it isn't). Got it on a good enough deal that I'm going to keep it anyway, but for those of you looking for Erect Image Diagonal, buyer beware.Also, while the 2" eyepiece holder is twist lock, the 1.25" is not. Again, for the price not enough to complain about and/or return for me, but if that's important to you, hope this info helps someone else like it would have helped me.
