Fantastic. I really like the features on the moon. I was out same time.

I saw the double shadow on stellarium. Checked the stars it looked twinkly. So avoided bothering on Saturn. But the double shadow was too tempting. Glad i did as mentioned briefly a little bit of calm was trying to come through. Didnt last too long. and started getting more variable

Btw how was the seeing your end ?

Same here, I was not planning to be up but I noticed it as well. I got a decent Saturn I think.

Superb capture Neil, some detail showing on ganymede too, i love multiple transit shots but never have always been lucky enough to catch them, again great stuff well done!

Btw what pane (roi) was you using as a capture window!

I usually use 640x480 for plenty of space. But with the moons i used 800x600

Cheers for the comments Simon. I know what you mean i tend to miss a lot of special events interesting capture moments.

Excellent capture, so much detail.

I was out a bit later, about 3:30 and there was only one shadow transitting.

Must’ve been Ganymede judging by the position :)

On my capture i can see two transits at that time was that 3.30 UT if so that explains it ?

Would be UK time :)

I was using a 6” newt, so I think the smaller shadow might’ve been too small for me to pickup, compared to your large newt.

Ah ok that also makes sense.

If I had a better Barlow I might’ve spotted it….do you rate Baader Q?

Ive not used it for visual. I screwed it straight into the ADC to lower the power a little. But for imaging it seems fine. as you can tell here its colour correction and sharpness seems ok

Stunning, detail on Jupiter is great but the detail on the moons! Excellent capture.

Thanks old fruit. i got deja vu. Many years have come and gone. We still enjoying the gas giant. its great for the UK to finally start getting it back. After years of losing it. We are all so much older now

very nice indeed. I watched the Io transit but got a little tired and called it a night.

Transits are always a great visual treat Skyhog. Glad you caught some of it. Cheers

Absolutely superb captures Neil the detail on ganymede is like looking at a mini mars shot as it is now.👍

Hi Martyn. I could tell looking at stellarium that the moon should show some detail. I was surprised by the fact that it shows part of the moon itself in eclipse. All captures are showing this the same. By the time I get to capture 9 it looks like Ganymede itself is coming out of the eclipse. Ive not imaged or noticed that effect before. A first for me. Something that doesn't happen a lot. At this old age. 

Thanks for the positive comments
