Hi all,
I continue to do battle against my Comet C/2014 Q4 (Lovejoy) images, trying to end up with a stack which has pinpoint stars along with a stack of the comet :bashcomp: I won't say how many hours I've lost to this! :lol:
Manual work using PixInsight and CCDStack haven't yielded any pleasing results (except simple stacks of the comet which look great). I returned to DSS this afternoon and came up with the attached, using default settings! Luck maybe. I did find I had to use raw dark and flat frames, seems maybe DSS can't handle the 32bit FIT master dark/flats I compile in PixInsight !? :confused2: (DSS would crash if I used them).
The DSS stack is 8x180s @ 3200ISO (Canon 6D)
I've also attached a stack which is simply 8x60s @ 6400ISO aligned on the stars.

Which is best? Well, they're different :shrug:
The battle continues ....
