Description

I am probably the first person ever to place two channels of monochrome images into a single monochrome image (I am unable to register correctly on DeepSkyStacker, for some reason, so any color images always have issues). The image above is 17 hours and 20 minutes of M27 in H-Alpha and OIII using a 14" Celestron Edge and an STT-8300MM. This final image is the final final image coming from the STT-8300MM, for we are now installing a ZWO ASI6200MM Pro on the telescope.
