To continue with the recent moon images I thought I'd add a moon from a different planet. This is Jupiter. The tiny red speck off the lower right hand side is one of the planets moons - Io. The dark blob on the surface of the planet to the left of the red speck is the shadow of that moon. Another three moons are also visible.
Taken with a small refractor (80mm f/7.5 & 2x barlow lens) using a webcam to record a small video of the planet and then the image was created by layering many frames together.

The mark on jupiter looks more like the Great Red Spot, seems a bit large to be the shadow of such a small moon, But don't quote me because i ain't got a clue about this stuff.
Yes, I see what you mean Brian. I posted this on a dedicated astronomy website and they assured me it was the shadow of the moon by looking at some Jupiter calculator based on the date/time it was taken. I guess they could be wong though. Tristan

Bit too centrally composed and not much foreground interest Cool shot and very interesting
Hi John, yes it was layered/processed with Registax and then tweaked slightly in PS for contrast. Its a very powerful little program. Really enjoyed your image of Comet McNaught back in January - I didn't get chance to get out and see that one. Tristan
