LtE in CMO #268

From Damian A PEACH

. . . . . . .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"!.

Best Wishes

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.


As already illustrated by others, producing high resolution images need not cost the Earth...


The Jupiter (on 5 Jan) is the average of around 550 images, while Saturn (on 3 Jan) is 1500 frames.

Subject: Christmas Eve Saturn.


Hi all,


As the weather has been so dreadful here this week, I decided to go back and re-work my best Saturn image, from Christmas Eve 02', one week after Saturn opposition. The result is attached. The information is as follows:

11" (28cm) SCT @ f/31.4 (0.23"/pixel.)

SBIG ST-5c camera.


Integrated Light (no IR rejection): ~160 x 0.35secs.

Red + IR rejection: ~30 x 0.60secs

Green + IR rejection: ~ 30 x 0.50secs

Blue + IR rejection: ~20 x 0.90secs


The seeing was good-excellent (pickering 6-10.) The bright storm discovered by Ed Grafton two nights earlier is present in the STrZ.


Hopefully the rain + 40mph winds will soon depart!.


Best Wishes
