I pushed this more than normal to see the OIII shell better. I also used some 600s exposures with my ASI1600MM at gain 200 which was the longest I had ever tried. I tried blending in RGB stars which is not something I normally do. I used some high pass filtering to bring out contrast inside the 'Owl' area. The background was difficult to control so it ended up darker than I normally like. Overall an image with compromises but a real learning experience for me.
