Are my artistic side is showing and I must agree with you Robert

Thanks for the feedback although there is 3hrs 41 mins of data shown here the data wasn't that crash hot to begin with, focus was a bit on the soft side, alignment between sessions was off so I had to crop the final I also had two ghastly reflection artifacts one in the top right and bottom left to remove

All frames where captured with a modified Canon 350d in Dec 2009, 4 nights apart , it was quite warm on both nights, 51 frames out of 62 stacked with darks and some flats but not enough
