I thought I would chime in,
I have been using the kstars beta 376 and tested last night, I was running a series of ten minute subs. and guiding for couple of hours, the sky did have some high very thin cloud waft through.
I was getting some oscillation with the dec axis, and I am not sure what caused it
My polar align is fairly good and scope balanced well
NEQ6 celestron edge800, OAG using qhy 178 guide camera
Stellarmate version 1.5.9, Kstars 3.5.5 (376 build) on windows pc. Ohhh also agression on RA was better at .9 too, I did try changing the dec, but did not see much effect. GPG was also engaged.
I have included both the Analyse and a phd logveiwer snap of results.
The guiding by the numbers looked great, but is that understanding what is the oscillation  caused by?
