Description

The data for this image was taken from heavily light polluted So. California over many nights from August 22 through October 29, 2104. I did not use a LPR filter just the standard LRGB. All sub-exposures were taken within 30 degrees of the meridian to minimize light pollution gradients, and the luminance frames were acquired only within 1 hour either side of the meridian near zenith.
Luminance - 73 sub-exposures @ 600 seconds Bin 1x1,
Red - 33 sub-exposures @ 900 seconds Bin 1x1,
Green - 34 Sub-exposures @ 900 seconds Bin 1x1,
Blue - 34 sub-exposures @ 900 seconds Bin 1x1

Revision B - Decided to go with the "grain". Used a different work flow with the goal of preserving as much small and large scale detail as possible.
