Description

Created this with a blend of the RGB - HOO off the OSC and a HOO synthesized version of the same image. By combining aspects of both versions,  I found the contrast and coloration I liked.

EXPTIME     = 22800 / Total luminance exposure time in seconds.      
LUM_EXP     = 600 / Average luminance exposure time.               
LUM_CNT     = 38 / Luminance images combined.                     
LUM_DARK    = 10 / Darks used for luminance.                      
LUM_FLAT    = 15 / Flats used for luminance.                      
LUM_BIAS    = 0 / Flat-darks used for luminance.                 
LUM_TEMP    = -5 / Set temperature used for luminance.
