First try at M27, though coma is still an issue as well as the guiding. Just received the Starizona SCT Coma Corrector/.63 Reducer. Hope to try it out this week. Working on the guiding.. where I seem to have significant Declination Backlash and very little southern movement when calibrating with PHD2. Fingers crossed I can correct this problem soon.
