Comet LoveJoy (1/19/15) These photographs are a stacks of 33 X 120s ISO 1600 (Top 25x120s at ISO1600) exposures taken with a Canon 600D and a Televue NP-127is. Subs were stacked twice, as comet aligned and then as star aligned in ImagesPlus. The two results were then stretched and combined in IP and the result was finished in PS using curves and some Carboni Astronomy Tools actions.
