Thursday, August 28th, 2008
Last night was interesting.   The "seeing" looked pretty good at times.   I would give it a 3/5, even a 4/5 at times.   I didn't find transparency very good, however.......at least while I was out, there were high thin clouds drifting around (10pm PDT to about 11:40pm).
 
Jupiter was a nice sight through my 12" Dob at 150x.   The Great Red Spot was close to mid-transit and clearly visible.   Well, clearly may be an overstatement.   I did find that a green filter popped it out quite nicely.   At 300x, the view was not as good......although you could still make out the GRS if you were patient.
 
I struggled again with the high magnification of the webcam and barlow combination.   It is just too much for my 4" imaging scope.   Focusing is extremely difficult.....wonder if a magnifying glass might make it a bit easier.   On my scope, a tiny move of the focuser can ruin the focus......very hard to get it right.    Below is a shot through a green filter.....very grainy!
 
I got a nice view of M57 in the Dob at 150x......but M53 was a disappointment......as was the vicinity of M31.

Thanks Jeff. Yeh, a 4" Mak-Cass. Unfortunately, it is barely adequate when the seeing is above average, and this year, above average seeing has been scarce. This photo would have been junk had it not captured the GRS.

The photo posted 8/21 is probably the best so far this year. There is a qwerk in the journal.....because of the low resolution of these webcam photos, you have to click on the thumbnail, then click again on the larger image to get a full resolution view.

I highly recommend downloading Registax. It does wonders with video clips that look terrible in raw form. It's free, and there are several tutorials online that make it very easy to use.

Did I read that right that your using a 4" scope for your imageing? I think thats a great image of jupiter through a 4" scope. Ive tried the webcam approach with no luck at all. Keep up the good work.

Jeff
