Description

September 2016

Blue Mountain Vista observing field (http://www.star-watcher.org/)

Almost 6 hours of data on this shark shaped nebula, yet, it turned out to be so dim that I barely pulled it out of background. I almost regretted I got myself into imaging it over the course of two nights at BMVO in September 2016. I had to apply several passes of noise reduction filtering and it took great efforts to get decent RGB balance. Amazingly, it seems that all those efforts have not created noticeable artifacts. Even the tiny galaxy in the upper left corner (PGC 68620) which I accidentally discovered on the image during the search for hot pixels survived the ordeal.
