LtE in CMO #267
From Brian
@ . . . . . . . . . . Hello
everyone...
I managed to
obtain a set of Saturn images on the night of 03 December, and have finally
finished processing them.
There is one IR
frame captured with the Pixcel 237 CCD, one RGB
composite from my Logitec Pro 3000 web cam, and an
IR/RGB composite. All images were
taken with my 30cm SCT. The IR
frame was captured at f24,
and the web cam was f28. Seeing was
quite good that night despite the bitterly cold -24°C temps and
moderate wind.
Please let me
know if there are any questions.
Take care,
(

dec 10 images
Hello
everyone...
I have attached
a set of images taken during the morning of December 10. I had intended to capture the transit of
the GRS, but I was clouded out soon after I started. Punishment for getting up at
All images were
taken with my 
30cm SCT at f28
and Pixcel 237 CCD. The upper image panel was taken in
hi-res mode, and the lower panel was taken in medium -res
mode (binned 2x2). The RGB set (poor quality) was
taken with the internal SBIG filter wheel.
A few
interesting observations. There appear to a short, wave like
segment of the STeB extending from the area south of
the GRS and continuing to about the CM.
The feature fades out at the CM. The feature is visible in the IR and
more so in the methane frame. The NNTeB also appears to exhibit the same appearance as the STeB, being visible from the limb and fading near the CM,
with a small white spot near the p. edge of the belt (spot noticed in methane image ?). The NTeB extends across the disk, but its structure varies -
thin and thick sections with a wave like pattern across the belt. There appears to be an enhanced colour
these two features, compared to the other belts, a blue tint perhaps?
Please let me
know if there are any questions or clarifications (my analysis is rather primitive compared to most of your
abilities).
Take care,
