The past Saturday morning we were very fortunate to havethe clouds

part just in time for the triple transit.



I scurried to get the ImagingSource DFK series USB, oneshot color

640x480 planetary camera and a good cable together. Ichecked that the

software was still working on the Mac, grabbed my eyepiececase and

headed down to the observatory around 10:30 pm, Friday.



We observed Jupiter through the 180 F7 for a while but Iwas anxious to

make sure we could get everything working, focused,exposure settings,

etc. Around 11:30 we mounted the camera to the 180 F7.



Here is the result from a 1 minute, 30fps video file. Iknow this is

nothing to write home about as far as image quality isconcerned but we

were only operating at f12.6. And seeing was not thatgreat. It was good

enough to get the shot and for that I am very grateful.That being

said, image scale, even for Jupiter, is an issue at thisfocal length.

Since we had 29, 1 minute files, I decided to try my handat an

animation of the transit.

You can actually watch as The Shadow from Europa andEuropa itself are

in sync in their movement. Callisto is to the left ofEuropa's shadow

and as we were watching this live on the video monitor, wewere trying

to figure out why we were seeing 4 shadows instead of 3.lol



Can't make out Io which is between the two shadows in thecenter to

right/top.



Right after the shadow of Io left the planet, the cloudsrolled back in

and a perfectly clear night went away in a blink of theeye.



We had a blast watching and capturing this event.

Congrats on the catch Mark and thanks for sharing. Many of us in the southeast US had overcast skies. ��:(
