a while back I dissassambled my Lx50 8" SCT for cleaning.
and when took off the main mirror I saw this arrow on the back... and wonder..
where should it point to ? In the past when I wiped a bit without taking off the mirror
it seemed to rotate a bit.. But now I wonder, where should it point? To the Focuser axis ?
to the corrector plate mark on the front of the tube?
I'm having very soft images even though My colimation seems good.
