Uranus - Sep 30th

I continue to try to image some surface detail on Uranus. The seeing did not cooperate last night, but I did get enough data to put together a composite image including the brighter moons.

The planet itself is an IR-RGB image, the IR being a 3600 frame stack from a 7200 frame AVI, 0.25 s exposure time, 3.75 fps (32 mins of video!).

The moons are from a 20 frame stack of 2s exposure time, heavily contrast stretched, and artificially apertured (basically, the relative brightness and positions are accurate).

I include a screen capture from WinJUPOS showing the orientation of the system at the time of capture.

Here's hoping for improved seeing some time soon!
