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

Hi Ray
A lovely set of planetary images. Very nicely processed, they have that classical “out of the spaceship porthole ” look about them.
Thanks for these gorgeous views!
Cheers
Dennis

That Saturn is a class result with the storm band showing well with strong edges.

Congrats Ray on these images. Mars is a standout, a really nice result, reckon you have done exceedingly well with it.
You may have had a less than great B channel for Saturn but that certainly doesn't show and your final result looks just great.
Very Well Done.
Regards
Trevor

Great results Ray. The Mars is fabulous - glad you got such a stunner this apparition. A very nice Saturn too, but there is possible even better to come!

Thanks Ivan - was getting a bit desperate after the seeing of the last month or so, so it was really pleasing to find some clear air before Mars receded too far. Regards ray
