Last night 11-07-2012 or 11-08-2012 U.T. was a very nice stable night of seeing, not perfect but likely 7/10...I did a few quick RGB captures, but this one around midnight...was the Best!
I captured the Great Red Spot (GRS) on the left, T
he GRS is a persistent anticyclonic storm, 22° south of Jupiters equator.
Also captured the Red Spot Jr.(Oval BA), a smaller cyclonic storm, just ahead of and below the GRS.
Near the Center of Jupiter on the (SEB) South Equatorial Belt is a small round object which is Jupiters Volcanic Moon Io, passing in front of Jupiter with albedo features visible on the Moon Io.
And on the right limb you will see a black spot which is the Moon Ios Shadow being cast onto Jupiters cloud tops...if you were on Jupiter under that black spot you would be experiencing a Total Solar Eclipse.
Jupiters Cloud tops can be very beautiful and you can see subtle changes nightly,and sometimes the colors can be vivid and sometime they fade, just like the red spots & Belts. Amazing that we can even see this type of detail from Earth with our small amateur telescopes! This is what makes Astronomy amazing & fun to experience!!!
After being at the Hospital all day with my Wife, I couldnt really sleep so to relax I had to do some imaging, i finally went to bed after this shot around midnight, glad I decided to unwind and image Jupiter.
I captured this from my backyard observatory in Dayton, Ohio using my DMK 21AF04 Fire-wire Camera & 10 SCT, 2X barlow, Astronomik RGB, 2700 frames stacked in Registax 6.
