Description

Backyard image from mustard zone. First edition is a little data anemic. Fist edition just a automatic background extraction, dynamic crop and histogram transformation in pixinsight.

Second edition added morphological transformation, curves transformation, and SC noise reduction to get green out, Plan to add more data.

3rd revision is after adding more data, total of 7 hours. Star field incredibly difficult to make less conspicuous. No noise reduction used, and wonder if the background could be darker. Hard to isolate the nebula since it takes up almost the entire field.

Happy with this object, ready to move on. Thanks for looking.
