Description

3 hrs on M83 Southern Pinwheel galaxy, but little did I know until all data was collected that a front had passed and high altitude atmospheric ice had appeared. As you can see, it affected star profiles, introduced an odd spike on brighter stars (not seen in my other images with this scope) and generally induced a very harsh green tinge to the image (mostly removed in processing).

Just making the best of those 3 hrs of precious time.
