GSO 8x50mm Right Angle Correct-Image Finder with Bracket
Great inexpensive right angle finder
Not liking to bend over to view, I wanted a right angle finder scope. This fits the bill perfectly. Nothing fancy, but great optics, great price.

GSO 2" 0.5x Focal Reducer
Eye Opening
I bought this 2" Focal reducer to give me more options when operating my camera for DSO imaging. I have not had a chance to use it yet because of the clouds, rain and cold temps up here in New England. It will give me F/5 straight up using my C8...

Celestron 1.25" 45-deg Erect Image Diagonal # 94112-A
Works as described for the right application
This does exactly as described. I did find, however, that it was les than ideal for astronomical use. I wanted a right view for public night and it worked just fine. Perhaps out of long habit, I felt the conventional 90 degree was more comfortable. F...

GSO 1.25" 2.5x Apochromatic Barlow Lens # BL251
Excellent value!
I compared the GSO 2.5x apo barlow to a TeleVue 2x I had. First, this barlow functions as a 2.1x barlow, not a 2.5x. In any event, on Almach, the beautiful pair was easily separated in my 17mm Sterling Plossl and looked simply beautiful, orange prima...

GSO 2" Photo-Visual Coma Corrector for Newtonian Telescopes
