Still have to go through the data.

Anybody out last night? Any success?
I think I saw the satellite eclipse event on the FireCapture Recording display as I was recording a SER on the Notebook, but then the clouds rolled in so I'll have to see what I ended up with.

The seeing was okay for the satellites, but not up to scratch for the Jovian disc.

Cheers

Good stuff. Can't wait to see.

While I was focusing on Saturn last night I saw something zooming past the fov in front of it but I wasn't recording. I thought bugger. I had been recording non stop for 10min prior and just when I focus something interesting happens. That made me remember Anthony Wesley told me a while ago that you can have a buffer set in firecapture for things like this. That you can go back to. You wouldn't know about that? One year later I forget all about UTC timestamps what are the odds I'd remember something like that.

Okay, here is the best of the bunch as we had banks of clouds that drifted through which played havoc with the recordings.

This one was taken between sets of clouds at 00:18:16 am AEST.

You can see by the general softness of the Jovian disc that the seeing was variable. I can also see diffraction patterns around the point-source like satellites.

The inset is a x1.3 up sample of the Ganymede Europa pair overlaid in PS CC.

Tak Mewlon 210 F11.5, Tele Vue 2" PowerMate x2 and ASI 462 MC camera.

Cheers

Dennis

EDIT: Just added another image, time stamped at 00:1345, some 5 mins earlier than the original, showing a slightly larger crescent for Europa.

That's awesome mate. Even got details on the moons.

Bit disappointed with the conditions but here's what I got: http://www.astropic.net/astro/occultation_20210822.gif

Ganymede up top Europa coming from the bottom. Jumps are missing segments from clouds. Seeing was terrible so it wasn't straight forward to process but you get the idea.

Very nice Marc, who'd have thought, a few short years ago, that amateurs, with modest equipment but extraordinary talent and dedication, would have been able to achieve such animation results.

I stayed at a lowly 4800mm FL and this is the best of the bunch so far from Brisbane.

Cheers

Hi Marc

I am going to give up imaging these events.

Have a look here:

Awesome animation.

Cheers

Perfect seeing. Heaps better than my two slimmy amoebas going at it. Got another 6 years to get a bigger scope

I just threw all my 1/2 decent files into Images Plus for an Auto Planet Align and produced this composite, using a Jupiter from a previous session.

The variations in brightness of the moons and gaps in their orbits are the result of bands of clouds passing through during the capture session.

Cheers
