Description

This image was obtained with the FLI 16803 camera on the 250cm /1250cmTakahashi telescope from my Observatory in Southern Spain. IC 1340 is part of a large supernova remnant called the Cygnus Loop. It is located about 1,500 light-years from Earth. Astronomers estimate the supernova explosion that produced the nebula occurred between 5,000 to 10,000 years ago. The image was generated with observations in the Oxygen [OIII] (blue), Sulphur [S II] (green) and Hydrogen-Alpha (orange) filters.When I took this image back in 2020 the FLI filterwheel shuttle got stick resulting in light licking in many of the frames taken, almost 50% from the originate exposures taken was damaged, including Darks and Flats.Giving this issue I had to work with Photoshop and Pixinsight.Total frames used 55 framesHa 900sec x 28 framesOIII 1200sec x 9 frames (20 frames damaged)SII 1200sec x 18 frames (10 frames damaged)
