G'day all,

 

Seeing was much better tonight, and I found a pair of captures of Jupiter that derotated well:

Jupiter 2019-09-11 10:44 UTC

Skywatcher 180 Mak-Cass

Fujiyama 12.5mm ortho (shimmed)

Canon T3i (LiveView capture)

2×1024 frames

 

The bleeing of dark red into the EB near the eastern limb was clearly visible on the laptop screen during capture—I even used it as the target for my reticle crosshairs to keep Callisto in the scene.

 

Cheers,

 

BQ

Thanks to all for the likes!

 

I took another crack at processing Callisto. The Lucy Richardson deconvolution on the full image caused some bad edge artifacting that I simply masked out in my first pass, but the result seemed too small and way too blue. I tried to do a moon-specific stack, but it was so dim in the individual frames that it wouldn't register in the stacker. So instead I just used the nominal stacks to compile a 4× Callisto stack with a Smart Sharpen in Photoshop. The results were better—at least the size and color now seem more accurate:

Great job, especially with the processing on that second attempt! I really like the way it turned out. The brightness of both objects seems to go together well, giving the overall image a very natural and smooth feel.

Thanks Anthony.
