Description

This was about a 3 week long project. I had some technical difficulties at first with calibration. Thanks to the help from John Upton on Cloudy Nights. He helped me out with some pixelmath that worked wonders on my flat fielding along with sharing other tech knowledge. I had a lot of over correcting with my flats. The large portion of work was done in PixInsight. This is my first serious broadband image. I feel as though broadband imaging is much more of a challenge for me compared to narrowband, especially with processing. I work from bortle 5/6 and narrowband image most of the time.
