Tonight I had another opportunity to observe Mars between 2:30-3:30am(6:30-7:30 UT) with the 6" f/5 reflector, binoviewer, yellow-green filter, and the Meade HD-60s at 231x magnification.
Seeing was more challenging this time, but was still able at times to see the SPC(tiny), Mare Sirenum(near meridian), Mare Cimmerium(toward the side), along with the NPH(unchanged) and some of the dark features around Elysium(Trivium Charontis and Phlegra.) I am pretty certain that the desert area I saw on my last excursion was Elysium now. I also saw somewhat of a darkening toward the edge of the SPC that I don't see on my map(mappa dell'Unione Astrophili Italiani drawn by Frassati and Tanga) unless it was either an optical effect due to the contrast or it was the mottled area between the SPC and Mare Sirenum. It was difficult to ascertain due to the seeing being worse tonight. Some other options that the darkness could have been were Palinuri or Thyle I, but I didn't know what those were until I came inside and looked at another Mars map. I'll put that map(Damien Peach's) on my phone for the next session.
