I just saw the blue halos on some of the stars. It was not apparent on my computer at home, possibly due to the gamma differences with a PC vs. Mac. I would dial that back given the chance.

I agree, this camera is well-suited to this role. My window on the sky does not really work with separate RGB imaging. The Kodak KAF-8300 sensor is used in a number of cameras very successfully including the black and white version that is still sold to my knowledge. It provides a somewhat smaller FOV than my DSLR, however, it still provides a very adequate resolution for my seeing conditions. Several cameras these days are coming in with much higher pixel counts, however, the images end up ...

Hi Val. A very nice rendition! Well done.

I tweaked this version a bit. I don't know what tool you use to process other than PS. With very large DSLR images, you are very likely over-sampling your targets due to the local seeing conditions. (The image scale of your imager and OTA should be around 1/2 of your local seeing conditions). With the size of your images, they will benefit significantly from software-binning the image.

I software-binned the image using ...

I forgot to mention that I did raise the gamma a smidge before the final step. Sorry I forgot to mention that.

With the Carboni actions for PS, I edited all or most of them to delete the conversion to 8 bit mode that he included in most. I only convert

I decided that this version deserved a place on my signature line.
