Hi.

Busy processing the rest of the avi's, but just wanted to get this one out of the way.

Ganymede and Europa formed a nice pair quite a long way away from the planet, so I can't give you an image of the moons in context with Jupiter, but here they are on their own.

I took an avi of the same area earlier on, and it didn't turn out very good because the seeing was only average. This avi was taken at 11:50pm local time, when the seeing had improved to be VERY GOOD!

Detail can be seen on Ganymede, including colour and an ice cap?

I'll go back and try and resample it up later on, but registax is busy with other things at the moment :)

Captured at 5fps, gain about 45%, gamma 50%, avi ran straight through registax twice - once aligned on ganymede and once on Europa. Both images saved, then split, LR deconvolution and recombined in AstraImage, and finally merged in Photoshop.

This is my best image so far of Ganymede.

Comments welcome.

Wow - that is excellent. It is visually quite stunning to see such detail on Ganymede, as well as the contrast between the two Galilean moons - the size difference is quite marked.

Well done Mike, glad you had a good night’s imaging come your way at last.

Cheers

Dennis

Excellent imaging Mike, Do you know what your actual magnification was?

Thanks.

Well done Mike!

The seeing must have indeed been very good to capture that.

But you still need the capture and processing skills to get a result like that.:thumbsup:

Now I think you might have some entries for next years SPSP, not content with the planet now he has moved it up a notch to throw DPeach of the world stage and has better images of the moons than he!

thanks h0ughy, but I expect when Damian Peach has processed his barbados images, there'll be images of Ganymede with detail we've never ever seen.

Well beat him to the punch and get yours up on APOD or spaceweather et al.:D :P

EDIT, I expect it there before tonight!

Here's a 1.5x mitchell resample version.

Not as good as I hoped, but it's ok.

Brilliant Mike, what great work. Ganymede looks better than some of my later Mars shots when it was down around 6 arc seconds:D

:doh: :doh: :doh: so last night when I decided just not to bother the seeing came good:doh: :doh: :doh:

(My first picture of Earth's moon looked a lot like that!)

Congrats, Mike.
