Io transit of Jupiter, 10/12/12

[JamesF]

Four of my favourites from last night's transit of Jupiter by Io. All Mak/SPC900, 50% stack of 1800 frames each.

Hi James.

Really nice captures and great processing. You really are getting excellent results from your SPC 900.

Nice work.

Cracking Image James I was watching the transit with my 80mm refractor until the cold got the better of me. I love the ones showing the GRS which I hope to have a shot at sometime soon.

Nice images James

You've really nailed the focus on them

Really nice pics. What did you use to put the 4 pictures of Jupiter side by side?

Thank you. It's a shame the entire set wasn't so well focused, but the seeing was all over the place. I was pleased to have the start and end fairly good though.

I used ImageMagick's "montage" utility. It's probably mostly known as a UNIX/Linux-based image manipulation package, but I think it's available for Windows.

Great job James! thanks for sharing.

Indeed! Nice set of images. Tells the story better than a single image.

How long was the transit?

[JamesF]

Two and a half hours, or thereabouts. I posted an animation of every frame I captured as well:

That is a lovely set of images

Very nice images - well done - it must have been pretty cold out there!

seriously nice work James, very impressive job (...with a webcam and the 127 Mak ?? ) very nicely caught !

[JamesF]

Thank you both.

It's just struck me, Io is smaller in diameter than the Atlantic is between, say, the west coast of Ireland and New York. Were it somewhere suitable, you could probably fly all the way around it in a modern passenger jet in a day. And (at the moment) it's six hundred million kilometres away. And we can see it and image a transit with a (relatively) cheap 5" telescope and a webcam. I think that's quite astonishing.

Great images James. Well impressed. Wouldn't mind a Mak myself.

Lovely images. I love the shadow cast by Io in the final 2 shots.

Very impressive.

Very impressive.

I must admit that I do like those two particularly. They really give a 3D feel to the image.
