M83

Posted By Jim Thommes
So M83 is a bit of a challenge for me here in northern latitudes. I did apply extinction factors to the colors to compensate for the low elevation (over and above that of my G2V factors taken near zenith). Color is always a challenge close to the horizon for me. Image and details are at the link below.
