looks pretty good for average seeing John - the seeing appears to have varied a bit over a fairly short term, but that happens.

The DEC axis looks like it has a bit of backlash (it has more variance than the RA and needs a few hits to correct some of the larger scale wander). That could probably be tuned out and there are guides on the web on how to do it. I think that you can check backlash using the check cal tool? For interest, does it have spring loaded worms?

If the guide variability is just down to seeing, the stars will stay round as the guiding goes to pot - they just get bigger
