M20, Help please
Hi again,
Strange last night, after M83 I turned my attention to the Trifid neb.
Capture 15 x 4 min exp, iso 1600 icnr off through my ed80 and eos 1000d. guided with phd.
Darks, Flats and bias frames applied.
The subs looked great on the laptop, Processing in either photoshop or gimp, I don't seem to be able to bring much detail out and I can see some dark artifacts in the neb.
My question is: Did I introduce the artifacts or muck up the capture or
anything else you may think of!
Thanking any and all in advance.
Darren
