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.

Nice work again Mike. It’s nice to see Jove so large again and you have captured an amazing amount of detail. Love the Ganymede solo portrait.

Cheers

Good stuff, Mike:thumbsup:

I was hoping you'd make the most of the seeing.

Keep 'em coming. With all my gear being packed away until I'm in a new house, I'll be on a diet of enjoying what you guys are producing:D

Those shots are astounding. It is extraordinary what you can do. Makes me reluctant to have a go myself.

Excellent Mike, beautiful detail there.
I'm glad you got good seeing, we had fog and haze roll in later.
Humidity was amazingly high up here last night.

I was testing out a lens and it was difficult to image in those conditions.

Thanks for your nice comments. I'm still processing the rest of the data from that night, there may be one or two others that's similar quality from earlier in the session.

Very impressive images. Thanks Iceman, you are inspiring me to get the gear set up and try some imaging. Have a web cam and laptop but still fiddling around with an adapter to the eyepiece.
Clear Skies

Hi Mike, I never fail to be amazed at your images of the Jovian moons the level of detail you achieve is fantastic.
