Jupiter isn't visible very long from my backyard, so I had to get out of bed early (at 4) to view the planet with my 4" f/15 refractor. It would be the first view of Jupiter through this telescope, so I did not quite know what to expect.

It absolutely stunned me! The view was crispy crispy crispy sharp and magnification of 300x were possible. The view through my 6mm ortho turned out to be the most pleasant.

Very distingtive was the bright patch in the southern(?) equatorial belt. And of course the shadow of Europa, which also made this observation the first shadow transit ever for me. Totally by change, I didn't know there there would be one!

Great sketch, especially for the first time out! I am enjoying flipping back and forth between yours and Jef's. Thanks for sharing it.

It's hard to get out of bed... but when you know there are other crazy guys doing the same thing, it helps :)
Fine sketch and report. It must be a hell of a surprise to see the shadow. I knew there was a transit, so no surprise for me.

Roel,

Congratulations on this record of your first shadow transit--these transits are very cool to see. Also very cool that you and Jef were out on the same night. :)

I will post my sketch from a few hours after your observation soon. Since Jupiter has not yet reached opposition (due in one month, Sept 21st), the shadow preceeds the actual moon transit. I did not see the shadow transit but did see the end of Europa's transit. [After opposition, the moon will transit first, followed by its shadow.]

Roel,

An excellent observation of Jupiter and a transit of Europa (II). You have recorded fine detail over the planet. The transit (Europa) is well rendered. Thank you for sharing it with us all.
