Description

Thanks to Bill Blanshan and Mike Cranfield's Narrowband Normalization process, my duoband one-shot color images have colors other than red!  Unfortunately, I have issues with distorted stars with my Rokinon 135mm lens that really shows up on this image.  I think I will try inserting a thin spacer to increase backfocus.
