Oh no! More M83
Knowing that M83 is sometimes referred to as the "Ruby Galaxy"...I decided to grab few hours of h-alpha only data (the seeing was appalling)
The result, to my surprise, clearly shows many of the h-alpha regions that are breathtakingly revealed in the Hubble image of this southern Belle.
With mixed success, I also layered this into my LRGB data...which nuked the colour balance..but with a little tinkering gave an interesting, but hardly accurate colour result.
Link to the results is here
