Wayne, Paul and Glenn, thanks for the kind words. Autorun is a great innovation, but focus is the obvious issue. But I find that nights of good seeing here in the mid-Atlantic have temp drops of only 2 degrees F or less, at least over the two hours or so that I'd leave the scope on its own (lots of trees).

Glenn - focus changes 1-2mm? Wow, the desert really is harsh! Even with temp comp, a good forecast and a good model, that would be awfully tough to deal with. I haven't worked on TC yet, but it's on the list.

And gamma is in WinJupos in the Derotate RGB Frames step. (I usually capture each channel at 80% fill on the histo.) I really ought to ask Grischa why it's like this, to make sure I'm not doing something wrong somewhere.

Last one, with Io, at 0701 UT. I think the color on Io worked out well, but there's not much detail. Somebody needs to do a tutorial on moon imaging!

And a WinJupos strip map of the whole night is here:

Thats a great map Kevin!

The best way to treat moons in my experience is to align on them separately, stack and resample at 2X or possibly more before applying sharpening. At a larger scale you can fine tune the effective psf more easily - too large and wavelets or deconvolution will simply yield an annular ring with a central dark spot. To convince yourself of that create a small circle of mid level gray, gaussian blur it a bit and try to recover using wavelets.

Kevin,
I would be interested to know more about the Winjupos batch mode you mention.
