Solomark 2inch Explorer Enhanced Dielectric Diagonal Mirror - Enhanced 99% REFLECTIVITY for Maximum View Brightness and Sharpness

not to be used in solar applications - will melt

This is my first 2" diagonal so I have nothing to compare it except a 1.25" diagonal. I use it on a Orion ED80 and I am happy so far. Its clear and the view is excellent. The only issue I had was that I had to tighten it more that what's required because it was falling off the focuser. Apart from that, I had no other issue. I used with 26mm and 15mm 2" eyepieces and it works fine. It's great for the price and any first timer can purchase with confidence. The product has a professional look, it doesn't feel cheap. Five stars.
