Wanted to see if my efforts are paying off.  Again we've had several days of rain and clouds but happened to wake up this morning to clear skies.  Seeing was only 6/10 and the scope was buffeting a bit in the surface gusts.

 

This is a 40% stack of a 24000 frame capture at 300 Gain and 5 ms exposure.  Still not there but this is the first time I've been able to resolve some details within the GRS.

I haven't checked yet but the spot on the left is the moon not another shadow.  Just haven't had time to look and see which one it is.

The moon is Callisto.

You can always tell the major moons by their colors, surface patterns and relative sizes. You just have to learn two sets, as the moons look different against a dark background (space) vs a light one (Jupiter's globe).

 

OP:  I'm not sure where you're located, but it may take many, many nights to have collimation, seeing and focus all play nicely together. And the seeing, at least, can vary from minute to minute. It requires an inordinate amount of patience in some areas.  Unfortunately, you can only collimate really well in great seeing and you can only focus really well with great collimation AND great seeing.  The trifecta is rare - the best you can do is to be prepared for it.
