Vixen R130sf focus
I've got a vixen newt and struggling to achieve focus. Secondary is square to focuser and aligned to within .5mm, it's all collimate spot on but can not get focus even on the moon.
I've search on Google for the scope and noticed some pictures have extender tubes. Would that be the only cause to not getting focus?
Looking down with no ep in the moon didn't look sharp either, I have an old Newt and looking into it there is a small moon but sharp in visual.
I'm stumped at the moment
