Hi everyone,
This observing session on the 23rd was a very good one here in Brisbane, got up at 1AM and watched the occultation of the Pleiades by the Moon with the 80ED while making images of Mars with the C9.25. It turned out the best seeing since months! 8/10 with a very good transparancy and after the imaging session I did also a good visual session, Solis Lacus was nice and detailed, still a prominent NPH. I tried to glimpse Olympus Mons as well, but that was still a bit too hard.
I shot 1 AVI of 5000 frames and 2 of 2500 frames @ 10 fps, the only problem with the big AVI is that Vidcap screwed up the header, but I fixed that with VirtualDub.
I also watched a few stars popping out from behind the Moon, and even at a 74.8 % phase the Earth shine was still visible!
Finally I went to bed at 5 AM to catch 1 1/2 hours of sleep.
I still had to limit the number of frames downto 4620, since Registax doesn't accept AVI's over 2 Gb. As I suspected the 10 fps AVI gives better results, as a matter of fact so much signal with this kind of seeing that the image looks almost overprocessed.

The NPH looks still massive.
I made another good observation a day later, but the processing of that had to wait until Wednesday.
Cheers,
Erwin
