Description

I've had a heck of a time trying to control the noise in this one. I think the ambient air temps were too high and the camera just couldn't get cold enough. I even went for a pretty deep exposure time to get more signal and reshot the OII & SII which did help somewhat. My earlier version, which I did not post, was imaged closer to the summer when it was much hotter and looked much worse.
