My Meade 12 inch classic lx200 is so far out of collimation I cannot focus on anything. my Zwo asi290mm mini cannot reach focus. pictures from it are just blown out white. no matter how I adjust the scope nothing can be seen (not even shadows). How can I find a reference point between the focuser ,the corrector plate position and the secondary mirror position. I am at an impasse. Any ideas you may have are appreciated. Tom Jackson
