Another session with Mars with better seeing than I had on 22nd, but for some reason I had a lot of difficulty with focus, especially with the IR filter. I used best 3000 frames from each of 7x6 min SERs (so 21000 frames total) for the OSC image and best 3000 x 6 SERs (18000 frames) for the IR image. The OSC image shows some nice clouds over Syrtis Major towards the limb and around the both poles. Elysium Mons is seen as a bright region at 2 o'clock, with maybe associated clouds right on that limb.
