My two objectives with this project were to try to show some of the subtle blue and red colour gradations as well as to bring out some detail in the structure. Most images of the Owl nebula show the owl head and eyes but there's more. It looks less owl-like with this resolution. Ha: 240 sec x 37, Oiii: 240 sec x 39, Sii: 240 x 39 for a total of about 7 hrs 40 min. RGB data: 180 sec x 126 for 6 hrs 18 min. SH0RGB has almost 14 hrs (13 hrs 58 mn) of integration.
