Jupiter Ganymede Shadow Transit and Great Red Spot 1-11-16

The seeing here in the Coachella Valley was excellent last night, so I had the opportunity to spend the night outside with clear skies, and my trusty telescope. It was quite cold outside, for the valley anyways, so hot cocoa was flowing like water. These are definitely my personal best images of Jupiter, so far! I was actually speechless while processing the videos, but that was more than likely the cold temps outside. I am quite satisfied with the results and I hope you enjoy viewing them. Clear Skies!

Image details - Each image is a 1600 frame video stacked in avistack with minor wavelets adjustments at the end. The first image is actually a composite of two, one for Jupiter and another with high gain to show the moons Ganymede, Europa and Callisto.

Jupiter, Europa, Io, Callisto and the great red spot

This picture is a stacked 3 minute video of Jupiter and 3 of its moons, Europa, Io, and Callisto. The software used includes Avistacks, Astra Image, and Photoshop. I recently came across the "holy grail" of telescope webcams, the Phillips SPC900nc and was blessed with near perfect seeing on  12-18-15 here in Cathedral City California. This webcam is amazing! The amount light it draws in, and the contrast is fantastic. My previous webcam was a Logitech HD c310, and I have to admit that the SPC900nc does a much better job.

As for Jupiter itself, it was shining at an apparent magnitude of -2.07. Europa is the top moon, followed by Io nearest to Jupiter, and Callisto is near the bottom. The great red spot is clearly visible in the image, as are the storm bands. The telescope used was a Celestron Nexstar 6SE.
