subs) - Las Cruces, NM Published as Astronomy Magazine Picture of the Day, 4 Oct 16 (screenshot). Published in Astronomical League's quarterly Reflector Magazine, Jun 2015 issue, pg 22 (screenshot). Published 2 Mar 15: - 6th slot in Space.com "March 2015 Night Sky Photos" (screenshot) 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. |
