I woke up at 3:45 AM to go out and image Comet Panstarrs on Friday, April 12, 2013. I should have got up at 3:00 AM instead. I didn’t think I would have problems in the field and I cut it way too close to the start of twilight.
What held me up is my mount wasn’t tracking at all at first and I had to haggle with it quite a bit before I could shoot some images. By that time, it was already 5:30 AM and the start of astronomical twilight was upon me. Not quite sure what went wrong.
I shot this with my Canon 200mm telephoto at F/2.8. Its only about 7 minutes worth of integration. I was hoping for 3 times that amount. Oh, well…
