I have a Meade DS 90mm refracting telescope.It fell and now I have a second,third shawdow.How to fix this? Factory set? Meade didn't help.
Did you break the mirror? --- or did you knock it out of alignment with the small secondary mirror in the front of the tube?
Contact someone at a local astronomy club to help you with collimation on the scope if nothing is broken.
