M27 - Dumbell Nebula
This is getting to be a habit! Now using Noel Carboni's tools, this is my 4th try!
Another attempt at processing.
Another processing session on this image (oh, what to do whilst its
daytime!) - this time, I combined using the Sigma Clip algorithm, DDP
processed, and then aligned and combined LRGB images. It
definately seems to bring out more of the nebulosity doing it this way.
Same image - reprocessed again to attempt to remove the sky gradient.
A crop, colour adjust, and unsharp mask of the image below.
