My second attempt at a time lapse video of Comet ISON, this time from a dark sky location on a mountaintop near New Market, Alabama, morning of Nov. 8, 2013.

I’m learning how frustrating astrophotography with a telephoto lens can be. This time I learned the hard way: double-check the focus!! Focusing on stars with a telephoto lens is difficult, especially when working at 400 mm focal length. This video would have been so much better with crisp focus, I could have zoomed in considerably through cropping.

I will try again in a few days, weather permitting, before the pre-dawn sky gets too bright. Maybe ISON will also brighten in the meantime. (After the video loads, it should loop by itself):
