Thanks all for the kind comments! Now hoping for another night or two a little like that one.
Dean, I loved that I could see a bit of Mars weather, clouds at north, south and Elysium. I'm married to a planetary scientist - this was one of the few of my astro images she really related to

She's not so fussed by nebulae...
Dunk, I don't think the seeing got any worse, but Saturn is fairly dim at that focal length, and so I think the difference in quality was all to do with exposure times being 6x longer. I ought just to image it at f/15, but the image scale was tempting... want to crack the hexagon!
