Thumbs up Jupiter + Ganymede, Europa and Io

Hi all

Here's one more processed sample from the 23 avi's taken in superb seeing last Friday. It's the last of the 23 avi's. Transparency was dropping very fast, as my mirror was covered in dew (the scope was pointing straight up!).

I captured 1 minute of Luminance (no filter) at 30fps, and 20 seconds each of R,G,B channels at 15fps. I stacked 850 frames for the luminance, and 290 frames for each colour channel.

I recombined the colour channels in AstraImage, and used Photoshop to do the layering, plus adjustment of saturation, colour balance, curves and levels.

I'm really happy with this image, with good detail on Io and Ganymede and Europa's nice and bright as it's about to egress.

There's a lot of detail around WSZ on the NEBn too. It's a shame I couldn't keep imaging until the GRS transitted but the scope wanted to do a meridian flip any minute now and I didn't have time to set it all up again.

I've finished running all 23 sets of avi's through registax, now it's a matter of combining them all.. animation coming today or tomorrow I suspect.

Thanks for looking!
