Pelican Nebula (Part 2)

Last week I posted an RGB image of the Pelican Nebula taken shortly after the full moon. The evening before (28/10) I’d had my first go at imaging with a Hydrogen Alpha filter, and a few murky evenings has given me the chance to process it and then learn how to feed it into the Red channel of the RGB image using Pixinsight. Updated image, along with the monochrome Halpha image, is below.

Really pleased with this output- because light pollution is suppressed by the filter I was able to expose for much longer (9 minutes per sub) and the red signal is correspondingly stronger. Once integrated into image you don’t have to “push” the software so hard to bring out the detail in the nebula.
