Here's a quick look at an image I made of Mars last night. I'm sure I can improve on this processing but I think it's worth a quick look - especially in this forum as it's got astronomy, photography and weather combined!


2010 Feb 21, 2254 UT. CM 180 degrees, diameter 12.8 arc sec. Transparency good, seeing moderate to poor.
Celestron CPC 1100, 2x Powermate, Astronomik type 2c colour seperation filters, Imaging Source DMK21.

This is the "boring side" of Mars - but note the white clouds on the right (preceding, celestial west) limb which mark the position of Olympus Mons and the other Tharsis volcanic domes. This is orographic uplift cloud, imaged from a mere 67.8 million miles distance!

Thanks guys ... I think my Feb 12 effort was better, this one was sufferring a bit from unsteady seeing & the corrector plate was steadily frosting over. I leave the dewcap on but turn off the heater when imaging at high resolution. This one does show the orographic cloud nicely though.

Last night was a "bust" for imaging - despite forecast for clear sky there was persistent low cloud till 11pm, the seeing was very bad (jet stream I think) & then high cloud spreading in in the early hours.
