Jupiter, Io and Europa

Not a lot of time for words this morning, which for those of you that know me, is a good thing.  Below is an image of Jupiter I took last night at about 9:15 PM MST (0415 UT, 1.14.14).  To the right of Jupiter are the moons Io (top) and Europa (bottom).

Image was taken through my C11 Edge with an ASI120MC color camera.  Seeing was average and I came a little closer on focus and collimation.  It may be time for a Bahtinov mask to achieve focus, and studying some real processing techniques.  Image is a stack of about 450 frames.
