The data consists of 3.8 hours of RGB, 1.3 hours of Sii and Ha, and 6 hours of Oiii. This is such a dim object that it was difficult to show the " squid" adequately, but Bill Blanshan's Narrowband Normalization script helped intensify the Oiii emissions significantly (with a mask). The RGB data were not used since the bright star on the right side of the image had a very large halo. The stars were produced from the SHO data using the method described in this video:
