Jupiter 22nd July with GRS and Io in transit

A couple of images of Jupiter showing the GRS region and Io and it's shadow in transit.

Cracking shots, love seeing all the pics of Jupiter here and these are fantastic.

Cant get over the apparent rotation in just half an hour. Need to research if that is jupiters speed, or our change in position relative to it as its blowing my mind up. Best view i've had so far i've only barely been able to make out a couple of lines and never isolated the GRS visually - need a barlow I guess.

Thanks for sharing

Nice images Peter. 🙂  I missed this one as a stubborn bank of cloud just never moved far enough away!

It is Jupiter's rotational speed, an incredible 10 hours for one revolution!

Many of the features shown in Peter's image are visible visually, not as vividly of course and it takes some work, but that night I saw the GRS and shadow very clearly, plus detail in the bands and also some of the blue grey festoon detail.

Great pictures Peter, it is really nice to have a reference to see what was actually there when I was observing at the same time.

Nicely captured.
