Title: Jupiter 20 Aug 2008
Post by: MarkS on Aug 22, 2008, 08:22:16

Raining this morning, so I decided to process some Jupiter data taken a couple of evenings ago.  And I'm still waiting for the moon to go away so I can do some deep sky stuff.

The seeing was pretty bad but Jupiter is (slightly) higher in the sky here in France, which makes a big difference.  Deconvolution has caused some ringing around the edge - I'll give the processsing another go when I get home.

500 frames at 0.2sec with an SPC900 webcame on the C11 with a barlow.

For interest, compare it with a very similar image taken 2 days before by a real master in Australia (posted on UKAI):

Hi Mark,

I think thats a really good attempt, what was it like visually ?  All I could see last night was the two main equatorial bands and just the barest hint of more detail - seeing was as usual c**p.

I almost can't believe that other image you posted, it's on par with those of Damian Peach - I think having a blueprinted C14 helps a lot !  Not sure about peltier cooling one though I would imagine that would be fairly difficult !

Very nice Mark. As Robert said, weather it's usual standard last night.

See what tonight brings......................

Visually I could see 3 distinct bands and I could also just about make out distinguish red spot.  But there were  definite waves passing over the whole image.
