Hi all
It's been 7 weeks since I've had the combination of free time, good seeing and clear skies all at once.
Last night it all came together, finally, and I was able to capture my first image (in seeing better than 2/10) since the 1st June!
Jupiter put on a great show in excellent seeing, and the seeing improved as Jupiter rose to almost overhead (76°). The GRS is very prominent in this image, and Ganymede's shadow had just finished transit.
40s each channel at 30fps, 600 frames stacked in each channel.
The second attachment is of Ganymede itself, taken in it's own frame a few minutes earlier. It's been resized 250%, but with very minor sharpening (minor wavelets) in registax after stacking. No other post-process sharpening was done, just noise reduction and levels/curves for colour balance and contrast.
It was nice to be back in the saddle. The skies are predicted to be clear all week, so hopefully the seeing will stay good!
Thanks for looking.
