The luminance channel for this image is a stack of 32 ten second 1x1 binned exposures using a 5" f/6 refractor.
A Gaussian histogram shaping was performed using AIP4WIN.
Each color channel is a stack of 16 twenty second images using 2x2 binning.
The color channels were balanced using AIP4WIN's Color Calculator using G2V star calibration.
The final image was composited using the G2V color balance.
