SPX350, PGRFlea3, Baader RGB, IR742, UVenus filter. Mars/Sat F39.1 Venus F27.5
Variable seeing started to settle for only one good Mars set, it took a while for the cloud to move so I was out a bit later. Saturn only gave one good set too before avg seeing settled in for the night.
I waited up till 6am local time for a Venus try with IR742nm and Astrodon UVenus filter combination - Venus is 20" and 58%phase. Wind stayed away fortunately, I found the UV filter hard to focus owing to the noisy image. The images needed strong sharpening to show anything. I think this shows Venusian cloud rather than sharpening artifacts.
Mars 1309hrs UT
Saturn 1312hrs
Venus 2000hrs UT
Thanks, John.
