Jupiter due south

Postby Aratus » Fri Jun 15, 2018 12:05 am

Jupiter is at its best right now - which this year isn't saying a lot. However there is still a fair amount of detail, and with Jupiter being so bright at the moment it is worth trying a little higher magnification. The Great Red Spot was right on the meridian as I started observing, although it had moved off by the time I took this photo. The North Equatorial Belt is somewhat thinner and darker than last year. The South Equatorial Belt seems a little washed out. (The one near the GRS)

Ganymede, Io and Europa are to the right of the planet.

This wider image is over exposed to give an idea of what might be seen through binoculars. Callisto is the object to the left. All these observations had to be done in a dark blue sky, of course.


btw The star next to Jupiter in the sky is Zubenelgenubi - a nice double star through a telescope or binoculars.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

Using a piece of software called 'WinJUPOS' it is possible to work out the current position of the Great Red Spot using an image. That figure can be used in planetarium software. From the images I took on the 14th June, the longitude of the GRS is currently 292 degrees.
