Hi all, first post so any help will be greatly appreciated. I recently bought a skywatcher 130pds (after the amazing reviews from almost everyone). I have a coma corrector and 600d dslr. Out trying to get started last night and could grab the moon n problem, yet when I moved to stars, focused with mask and raised exposure time it didn’t do much good. I have basically a single dot as a star. (also have a clip in LP filter) which makes me think I’m doing something wrong or missing the point. I went from 30 secs - 1:00 and still doesn’t seem to collect any more. Thing I’ve noticed is my aperture setting on camera says it can’t be set as there is no lens but I’m into the focuser on the scope?? I’ve attached a few photos to try and explain what I mean. Again, any help would be greatly appreciated.
