Mars and Saturn 17Mar in useful seeing
At last - just when I was going to lock the scope in the shed and take up a sensible hobby, the wind blew up from the east, with a nice smooth flow off the sea. Even with a low grade 50kt jet at 200hPa, the seeing was OK for a change and I could see some albedo detail on Mars - better than hoping that deconvolution would dig something out after stacking. The increasing wind eventually became the enemy and destroyed the seeing before Saturn got to maximum altitude, but the red and green channels looked good lower down anyway (and blue was remarkably bad).
Typically stacked 1/4 of frames for Mars and up to 1/2 on Saturn, using AS!2.
Mars is showing some beautiful cloud over the Hellas impact basin and there is some interesting white ice? outside the dark collar around the polar cap. Saturn was imaged within 6 minutes, so it's slightly noisy, but there is still some hint of continuing structure in the region where the storm was.
That was good fun - thanks for looking. Regards Ray
