Io shadow transit

[Athena]

I have just observed my very first shadow transit

The transparency was dreadful with lots of broken cloud but despite this I was able to clearly see the dark shadow of Io as it crossed Jupiter’s disk. I looked very hard but was unable to see the actual moon. Is it possible to actually see the moon during transit using a 8" F10 SCT?

Unfortunately Jupiter kept disappearing behind cloud so my observation was limited. I attempted to image the transit but by the time I got my camera setup and focused a rather large cloud bank refused to move.

Oh well, next time...

Congratulations, well done! The first time i ever saw a shadow transit on Jupiter (newbie, 1998, 90mm ETX Mak) i thought it was the GRS... seems a lifetime ago, lol. But even now with my 'big girl' scope (also an 8" f/10 SCT) i've never been able to detect one of Jupiter's moons as it's transiting. Have to admit though, i'm really not much of a planetary observer. Hope you see one some day!!

That's thebeauty of the transits, there will always be another one along soon, weather permitting of course.

Depending which moon it is as where its transitting on Jupiters disc (for colour contrast) they can be quite easy to see if conditions are reasonable. I've seen them with 4" refractor.

Should be easy in an 8" SCT. Jupiter has such alot to offer the imager/ visual observer. I actually got a shot of it, i`ll post it when i`ve processed it...
