Data collected over two different years (2012, 2014), this image is LHaRGB, where I combined data I collected on 26 Nov 14 with RGB data from 26 Jun 12. I used L:Ha (50:50) for the Lum channel, all other channels 100% each, with a blend of RGB from each of the two different years. The orientation is rotated 180 degrees from my 2012 result to better present this planetary nebula's outer emission areas.
