ED80 Cant get into focus
Hey there,
I need some help here,
Is it normal for my Skywatcher ED80 Pro Series (Skywatcher 1:1 focuser) to not get into focus with a GSO 2" (Or the small GSo Plossl) Eyepieces directly place into the back of the focuser??
I try to back off my Eyepieces and I can get the image into focus but the focuser wont be holding the eyepiece at all...
Thanks for your reply
