      5.0 Best buy


      Incredibly bright image, totally black inside.


      Mirror box finish rubs off fairly easily.


      This unit may well be the absolute best value in a mirror diagonal. The image is incredibly bright. The unit seems larger than the normal 1.25" diagonal. It is fully blackened inside and out and threaded for filters. I bought my first one to use with my Astro-Tech Apo refractor and I bought another one for my 6" SCT as well.
