Jupiter June 16

Hi all,

Two shadows on Jupiter so, of course it was cloudy when I got up to image. Jupiter was just showing through the clouds so I decided since I was up anyway, I'd give it a go. I had to increase my exposures from about 25ms to 60ms, cutting my frame rate to about 17fps. That only allowed for 900 frames instead of my normal 2000. Luckily seeing was not too bad and here is my result. I see what looks like a reddish spot in the north polar area (bottom, right) and the new dark spot is prominent. I'm not sure what the brownish area is to the right of the dark spot. The two shadows are Io (right) and Ganymede (just coming on the disk). The moon is Io. Still trying to figure out the best settings to capture detail on the moons.

Paul, great double transit images! In the right shot, Io looks much better RGB aligned than Jupiter. Ideally, should the globe be RGB aligned separately from the moon? Seems like the capture conditions on the right image would get some details if you had better seeing.

Very nice detail Paul. I'm looking forward to Jupiter being higher in the sky this year. Last year was a little tough to get a good shot.
