Comments: Mars this year is quite frustrating, this is mainly due to the low altitude found for most imagers located in the southern hemisphere. Even so, I can't complain because I'm getting to Mars with almost no Edge Ring, which is quite common and I've noticed in the photos of most of my colleagues here in Brazil. I myself don't have an exact idea why this happens, but I firmly believe that the C14 at f/22 with the ASI 290 is the reason for this artifact-free result. I believe that if I used the 224 with a larger pixel it should manifest itself, but unfortunately I don't have one to test my theory.
