Review on Celestron Erect Image Prism: Enhance Clarity for Refractor and Schmidt Cassegrain Telescopes by James Crofton

I bought this to extend my 80mm short tube Orion refractor. It is currently mounted on my Meade 10" LX200R as a directional sight. This diagonal allows me to use it as an intermediate viewfinder between my 9x50 and my main OTA. The quality is what I use it for, although I would do it how inside there is a ring clip to hold the eyepiece, only the tip of the locking screw is used instead, the same as most cheap scopes and star diagonals, so if you have good eyepieces be careful: they leave a mark.
