After the first-light version of Pickering’s Triangle we collected a few hours more data of this fascinating part of the Cygnus Loop. This combined set of 15 hours of H-alpha and OIII narrowband data allows to bring out all the intricate structure in this supernova remnant. <\/p>\n\n\n\n

To emphasize the nebulosity even more, the stars were removed from both narrowband channels using StarNet++ before further processing and combination into a bi-color image. Make sure to look at this image in the full-screen viewer!<\/p>\n\n\n\n

The animation below shows the individual narrowband channels as grayscale images, then the combined bi-color image, and finally the same image with star added back in. It shows nicely that the spatial distribution of H and O gas shows a different morphology. <\/p>\n\n\n\n
