COMMENTSThis image was selected as the March 12th, 2009 NASA's Astronomy Picture of the Day.This image comes from the same data as the previous image except that this one includes over three hours of Ha data.
After being done with the previous image - where I could barely use any Ha -I told Ray I would like to capture one night worth of Ha only. This time, Ray capture the Ha data himself and when he was done he sent me the calibrated image. I added the Ha to the LRGB I already had and reprocessed the image. Later Ray sent me the image as he processed it. I took that image, extracted the lightness data, blended it with my previously processed HaLRGB image, did some additional processing, and the result is what you see.The highlight of the image is the interesting planetary nebula at the bottom-left of the image. It was identified as PN G227.1+00.5.
