Jupiter February 17th

Last night was the first clear night in several for us here in Tucson and I spent a few hours observing.  In addition to some typical targets, I observed the Supernova in M82 and was pleasantly surprised to see that it has dimmed only slightly.  It was still easily visible even in my 90mm refractor.  Using the 11 inch SCT, it seemed to have a slight yellow cast to it!?!

Of course, I also took an image of Jupiter under average seeing conditions-  and to my surprise, there is a very interesting feature on the "boring side" of the planet...a disturbance that is nearly as large as the great red spot and is also a shade of red.  It is more stretched than typical storms, and it will be interesting to obsreve how this region changes and how long it persists.  The image below was taken through my 11 inch Celestron Edge HD SCT with an ASI120MC camera...it is approximately 250 frames aligned and stacked in Registax with some tweaks in Photoshop.
