| Comments: | Data acquired in 2012 but processed only this year! I've subtracted as much light pollution as possible but that has the effect of "amplifying" the red glow at the bottom. The stars at the bottom of the image have not stacked properly because of differential atmospheric refraction between the subs. The smeared cluster M6 at the bottom of the image is only 5deg above the horizon. So there's a lot wrong with the image but I still like it. |
