Thumbs up April 4th UT Mars & Saturn in good seeing.

Hi All,

Imaged Mars last night in reasonable seeing , have good coverage from CM 138 to CM 160 which I think is the region of interest for Wayne’s cloud.
Have attached 1 RGB & 807nm IR data set along with animations of all RGB & IR data covering 90 min’s of Mars rotation. Olympus Mons is well resolved as is the Propontis Complex and the clouds over the Tharsis volcanoes. Reckon this is about the best resolution I will get at this alt as Mars continues to shrink.

Moved on to Saturn and the seeing was good, this is the best 807nm IR data I have ever captured of Saturn, such a shame that there are no SED’s active now. Have attached 1 RGB & 807nm IR data set along with animations of the best RGB & IR data. In the RGB animation there is some nice structure along the Southern edge of the great storm remnant and there are some faint clouds in the NEB, this is also remnant material from the great storm that has been distributed further South by the interactions of the various opposing jet streams that frequent the Saturnian atmosphere.

The IR animation at first glance looks a bit bland but of interest is the ripple along the edge of the intersection between the EZ & NEB. A closer inspection shows movement of spots within the NEB that are associated with the features appearing in the same region in the RGB animation.

Thanks for looking.
Regards
Trevor
