® . . . . . . .Here are some Mars images from December 26th, 30th and Jan 2nd. Elysium has been followed across the disk, looking bright, with bright clouds over the Cebrenia area also. This morning, Elysium also appeared bright, as did Olympus Mons on the p. limb. The clouds over these area have also been observed visually, I'm looking forward to Feb 25th, when the apparent diam finally reaches a more respectable 6"!.

Please find attached two results (of Jupiter and Saturn from this month) obtained with a $60 Philips webcam. The Jupiter result equals the best results obtained with the cooled ST-5c i also use.
The Jupiter (on 5 Jan) is the average of around 550 images, while Saturn (on 3 Jan) is 1500 frames.

Red + IR rejection: ~30 x 0.60secs
Green + IR rejection: ~ 30 x 0.50secs
