Revision: H

Title Reprocess

Description I was finally able to incorporate the Ha data into the bg of the image with Jürgen Terpe's "Combine Ha with RGB" script, and I have changed my method of correcting, stretching and rescreening RGB stars. The crop is slightly sider to showcase the improved background.
