Telescope Reviews: Double-moon + GRS/Red Jr transit

Hi all

This image was from earlier in the evening (6:03pm) before the shadow transits had begun.

Io had not long crossed in front of the disc, and Europa is not far from leaving the front of the disc.

Seeing was fairly ordinary, and fluctuating wildly - mostly due to boundary layer and tube currents as the temperature was dropping after sunset. I took 9 avi's, but this was the best of them, and in all cases I couldn't get 3 good channels.. I always had one acceptable channel, but then the seeing deteriorated while capturing the others.

Stacked 180/1300 frames in each channel (over 3 alignment points), usual LR deconvolution and recombine, followed by curves and colour balance adjustment in photoshop.

I captured a few avi's as Europa's shadow begun to transit, but by then the seeing was even worse. I might finish processing them and post them later. I didn't get to capture the double-shadow, as Jupiter had dropped below 50° in the west, where I can't see it anyone thanks to house + trees.

Thanks for looking.
