Jupiter, Ganymede & Europa

[Davide Simonetti]

Double exposure of Jupiter with two of its moons - Ganymede in the top right of the frame and Europa at the bottom left. The Great Red Spot on Jupiter is just visible in the southern hemisphere of the planet. London 24 November 2014

nicely done, you don`t usually get the moons as they can disappear when processing, was it taken with your zwo camera ?

Thanks...yes this was done with the ZWO ASI120MC. It's a combination of two images. I exposed first for the moons, overexposing Jupiter and shot 1000 frames, then I quickly changed the exposure to bring out the planet (thus losing the moons) and shot another 1000 frames. When I got home I processed both videos with PIPP and Registax avoiding any cropping. Finally I put both images into Photoshop as separate layers, tweaked them a little and combined the best bits of both. It's something I've been wanting to try for a while.

Nicely done Davide, lots of detail showing there. I noticed you put 24th November? - Today? Did you take this at the native focal length or use a barlow?

Hi Harvey,

Yes this was done this morning. I wasn't expecting a clear night and I was ready to curl up with the heating on, but Jupiter was so bright when I looked through the window that I couldn't resist so I braved the cold and started imaging around midnight. This shot was done just before I packed up at around 3am.

This was done without the 2x Barlow because I was trying to bring out the moons (I didn't manage to include Callisto which was a little way beyond Ganymede). Earlier on I did some closer shots of Jupiter using the Barlow and once I've processed a few I'll post one up
