Jupiter on Saturday night. The seeing was reasonable but the wind upset things - the gusts were blowing Jupiter all over the place within the frame. It made it very difficult to tease out the details on the surface. With the dewshield on, the scope was buffeted far too much and with the dewshield off, the corrector plate misted up in about 10 minutes.

Looks good regardless of the difficulties. I love the swirly bits below and right of the Great Red Spot. The resolution of my 8" just won't resolve that sort of detail - not from thermally active Beckenham anyway!
I'm surprised the corrector misted up with a breeze blowing, was it definitely on the outside? I have had damp inside the OTA cause fogging no matter how high the dew heaters, the OTA had to be opened and left in the airing cupboard for a few days!

Good point - it may well have been on the inside.
I'll dry it by lowering my bag of dessicant granules into the scope down through the baffle tube.
