I'm not sure if it needs it. I need to come up there and get the 8" so I can sell the fork mount and buy the dovetail plate to put the OTA on my Losmandy GM-8 mount. I also need to buy a 2" visual back so I can use my 2" EverBright diagonal and Nagler eyepieces with it. I'll probably come up to Utah County after first quarter moon. The 8" hasn't seen alot of action with competition from the TV-102 refractor and the 15" Obsession. But I would like to try splitting some tight doubles with it. Clear Skies, Debbie
