Jupiter with double Moon and Shadow transits

The clouds cleared just in time last night to enable me to capture these transits.
Two shadows plus three moons: Europa is the faint white speck, barely visible in front of Jupiter near the left hand side of the limb. Ganymede is the dark central spot and Io is approaching Jupiter on the righthand side. Io was eclipsed by Jupiter shortly afterwards.
Taken with Skywatcher MAK127 with 2X Teleview barlow to give 3000mm focal length. Not great resolution - needs more aperture! Capture in SharpCap, stack with Autostakkert and sharpen with Registrax.

Glad to see that someone had clear enough skies to capture the transits, thanks for posting, more aperture would be better of course. Was cloudy and raining here, most frustrating, just hope that the conditions are favourable for the 15th/16th transits.

Nice!

Had a clear night, but very average seeing. The events were beautiful visually. I did have a go at getting some data/video which I will process and post later. It was difficult switching the Bino’s to a camera…my brain just resisted…Just a little longer please!

Thanks Jeff,

I am keeping everything crossed for the 16th.

Thanks Hemi.

I know what you mean: visual experience vs imaging. Last night was an experiment for me.

I plan to visually observe the entire sequence of moon and shadow events on the 16th. It will be a truely remarkable rare sequence if we are lucky enough with the weather. I find these are etched in my memory and easily recalled. A series of less than perfectly sharp images simply does not compare.

For the 15/16th I shall be setting up the imaging rig and a visual scope along side, so in between capture runs I can just pop over to the bino viewers in the other scope. No harm in trying to get the best of both worlds, should be fun.

That makes sense Jeff.

I'll try the same.
