Hi
my latest NGC 253.
I've had so many goes at processing this one its not funny...
in the end i found that doing very very little to it seems best.
This is straight from stacking in DSS (with flats, darks, bias, cosmetic 1%)
Slight adjustment in levels, slight crop for centering, a bit of saturation, a pinch of salt...oh wait that's another recipe... a bit of unsharp mask and that's about it.
no high pass filter, no noise reduction etc...
thanks for looking
frank
