the attached image uses 3 300second luminosity images and one each 300 second Red Green Blue image.
While I've been using Pixinsight for awhile I just do basic things ABE, BN, CC and histogram correction.
So I don't know how to deal with the noise ring I'm seeing, which is strongest in the R frame.
I could select the region and drive down the signal until the noise is black but that gets rid of the real signal in the region.
Is there some way in Pixinsight to eliminate the noise band--actually it's probably caused by some optical defect or an external light source--without eliminate the actual scene signal?
Thanks for any help!
