Description

This image is a total of 192 5-minute exposures with a dual narrowband filter on two consecutive nights.  Both nights had excellent seeing conditions. It was processed in Siril using the Ha/OIII OSC Extract Script. The resulting stacked monochrome files were combined using Pixel Math. The Red channel is the Ha data and the Blue and Green Channels are OIII. I did not use a formula to arrive at the green channel unlike the previous Lion Narrowband image. For that image I used a 60% Ha + a 40% OIII to arrive at the Green channel. Quite honestly I have not experimented enough to understand the impact on color based on a given pixel math formula.
