The best image I've taken of Jupiter yet. Captured 3 out of the 4 Galilean moons and the GRS. Unfortunately by the time I got everything tweaked, I had about 10 mins before Jupiter was out of view. I was only able to capture about 90 seconds of data in my best data set before the night was over. It would have been nice to capture a high exposure of the moons and superimpose it on this image.

 

Seeing was quite good thanks to the hot, still air the Pacific NW is seeing right now. Captured a lot of detail in the bands. Really impressed with the capabilities of this 12" scope.
