Took some image with my C14 Hyperstar + EOS 60Da (32x30s IRRC) and trying to take the drizzled and pcc'd linear image through deconvolution/denoising and stretching. I think I am reasonably proficient with star masks now (I do miss a few double stars....seems like a lot of trouble to refine to get those last bits, is this typical?) and tried to create an appropriate deringing support as advised here:
http://www.pixinsight.com/examples/M81M82/index.htmlNo matter what I do, I can't seem to to improve the image with deconvolution. I can see "too much" where it looks like it is being stretched around noise or what looks like next to nothing. I can't see the same sorts of visual contrasts that are in the tutorial. An important issue:
When I create the external PSF, the star profile is not round; a brutally honest reminder that the collimation is off (I've been trying to fix, but having a hard time). Does the poor collimation affect how deconvolution will perform? E.g. Will it try an model collimation error in the underlying model that is based on atmosphere?
Are there any other image issues that stand out? Note I only correct with bias and flat due to the way the Canon does darks.
I've included masks in the zip file (1G):

Nice to see that there is some comparable detail in the data...I wouldn't know much more than to do pre/post denoising in the dark and a little bit of saturation and brightness adjustment. Should I be able to do much better with this data? I swear I see a bit the IFN when I compare to other pictures, but it is quite faint and not sure if I can successfully pull it out.
