Description

This is from earlier this year, 2017, from Deep Sky West's Rokinon 135mm lens on CCD camera with filter wheel setup in New Mexico. In addition to the subframe count (142 x 300s) is an additional set of 47 x 600 second Ha exposures used in the luminance image. For this image I only used the Ha integration averaged with all the other channels (LRGB) into a "superluminance." I did not incorporate the Ha in the red channel for this image. I have an alternate version with the Ha merged into the R channel image.
