Experimenting a bit by combining my HST image with LRGB data I captured at the Illinois Dark Sky Star Party. I will separately process the LRGB data this weekend. I blended in a 7/3 ratio favoring the color data.
Lots of different data went into this image from a 17"-CDK down to a 3" refractor. The data I captured with the CDK and CCA were done with the club's equipment (TCAA).
