Hi all
I didnt think the raw images I took of this were all that good, but upon processing found the final image was better then expected.
Its 3x 100 sec ISO 1600, with 10 inch F5.6 scope, uv/ir filter. MPCC.
A first for me, I used ABE to generate an artificial flat field, then used IRIS to divide that from the image, and amazingly it got rid of all the gradient and vignetting. Ive been hearing of others here using it so thought Id give it a try. If it works on future images as well, I may never take a flat field again!

and is free. I just used it at default, using its generated model as the flat field.

B86 has always fascinated me, an inkblot in space is what it looks like, with a pretty open cluster thrown in for value.
