Description

Images captured from my Bortle 6 back yard in Vestavia Hills, AL on December 5 - 7, 2023.  Broadband frames were taken under moonless skies.  All subframes were at gain 100 and 0 degrees C, gain 100, bin 1.

This was my first attempt at using PixInsight's HDRComposition process.  The final RGB image is a combination of 30, 60, 120 and 180 second RGB masters.  The tool was also used to combine multiple Ha masters (300 second and 600 second).  The luminance master was a combination of 60 and 120 second masters.  Ha was used to enhance the red channel and the luminance master.
