Manilius--Errata

Posted By Mike Wirths
Hi all,

I couple days ago I said this image was the crater Calippus, but after carefully checking Lunar Orbiter images, I discovered it was Manilius. Manilius is 39 km wide with very steep walls. To the lower left of the image is a dark halo crater (DHC)which are possibly volcanic in nature with a dark ejecta blankets.
I reprocessed the image and dug out more detail.

cheers

Eric,

Gorgeous Saturn image! Impressive banding and ring detail!
I have a question for you and the other experienced Saturn imagers out there, is'nt the period of rotation of Saturn almost that of Jupiters? If this is so would'nt longer image times blurr out fine banding detail like small storms? I guess this is where the firewire cams and the lumenera have an advantage with their 30fps.

awesome Eric!

Saturn in B&W--weird lines?

Posted By Mike Wirths
Hi all,

Tried to image Saturn the other night, the plan was to shoot the L vid then swap out the Atik B&W cam with the Toucam to shoot the colour portion. Trouble was that the seeing was basically really crappy, so I gave up at about midnight.
After aligning in Reg 2 and processing I noticed lots of vertical lines running through the image, this was apparent even in the stacked raw image. When I selected the avi I checked off the interlace box as usual, what gives? Is this effect caused by the really poor seeing? I did'nt get this effect when doing lunar shots (well I did if I pushed the processing too hard, but they were of much less magnitude).

still surprised me for really crappy seeing that it shows as much as it does.

Saturn--my best

Posted By Mike Wirths
Hi all,
Well I was looking forward to last night as the clear sky clock was predicting good (4/5) seeing, pretty rare for here!
By 10:30 the seeing did indeed have tantalizing moments of great seeing but they were very fleeting and a lot of the time it was distorted. Consequently I could only salvage 490 frames out of 2800, the best frames were amazing just not enough of them. So the enke is there but the globe is noisier than it should be, still its by far my best yet and I'm happy with it!
As a side note I finally saw the Enke gap visually!! Just before I slid the Toucam into the 5X's powermate, I had in a Takahashi 7.5 so that works out to 1300X's, and I caught the enke distinctly for a split second several times, very exciting! A testiment to the 18" Zambuto mirror!

cheers
