Mars Saturn April 2nd UT

Hi
the high level winds backed off below 50 kts last night and the local seeing was OK when the clouds allowed - nothing special, but good enough to image.
Mars seeing was fair overall, with a lack of finest detail being the main problem - lots of magnificent clouds on the planet though.
Seeing had fallen off a bit for Saturn and this image was taken at about f22 to bump up the capture rate.
Stacked in AS!2 - typically 20% on Mars and 35% on Saturn, both with 1.5 drizzle stacking. sharpened in AS!2 with additional light VanCittert deconvolution + median filter in IRIS and scaling and colour touchup in GIMP. Colour balance for Saturn via "white" function in IRIS operating on a section of B ring.
thanks for looking. Regards ray
