Sweet Home Alabama Transit of Jupiter by Io

Last night I took over 25,000 images of Jupiter to capture the transit of Io and its shadow across Jupiter. I'm on a road trip in Madison Alabama, just down the road from the Space and Rocket Center. The clouds from the last front cleared out yesterday. The seeing was very good with only a little variation in transparency.

It will take some time to process all the images. I'm headed to the Mid-South Star Gaze in French Camp, Mississippi tomorrow. I decided to do a preliminary stack of my last set of images to get an idea of what I have.

Questar 1350/89 mm telescope with Dakin 2X Barlow and ZWO ASI120MC planetary video camera. Exposed for 83 msec at a gain of 41. Taken from Madison, Alabama, 2017-04-26 05:42 UT. Best 128 of 2000 images stacked in AutoStakkert!2, deconvolved in Lynkeos, with final exposure and crop in Photoshop.
