Not quite--you posted the log in such a way that I can't download it, because you didn't put it in the Public folder (my fault, I should have told you that). So I could only download (cut and paste) part of it.
Still, it was good enough to get an idea. (The first log is useless BTW, just a failed calibration. The second log starts with a failed followed by a perfect calibration).
I snipped out the bad regions to get an idea of the true performance when you are *not* losing the star and causing disasters.
I was able to see the full first section and about 45 mins of the second.
On the first section you had about a 2.39" RMS (poor, and mainly due to two *additional* spikes--walking near the mount? touching something?).
On the second section you (after removing the bad region) had a 1.38" RMS (probably a bit better as it *still* included a spike that I didn't bother to remove).
The second result is about what I was getting on my CG-5 and can produce round (if a bit bloated) stars. You can improve on it a bit more when it's not windy, seeing is good, etc. But it doesn't appear to be due to any major mount or guiding disasters (except the spikes, probably due to clouds). I think your parameters will let you average around 1.1" guiding which is less shabby than it may sound.
Some comments on your parameters:
Exposure: You have 1ms. If you record and enable PEC, you should be able to increase that to 2 or 3". This will make you less dependent on seeing. You can also try (instead of recording/enabling PEC) to use the PPEC instead of the hysteresis algorithm. I would experiment with the following 4 combinations:
Hysteresis at 1", Hysteresis at 2", PPEC at 1", PPEC at 2", PEC (mount) at 2". However the improvements won't be drastic--you may get it down to 0.9-1" this way though.
RA: see above re algorithm. I assume the MinMo is from guiding assistant (seems reasonable). Hysteresis % seems reasonable and aggression as well--maybe raise to 0.8 or 0.9 because it looks like your RA doesn't quite catch up.
DEC: Consider guiding in one direction (North or South, not Auto) since you've disabled backlash compensation. The logic is that you're never *perfectly* polar aligned, so you only correct in the direction of drift away from the pole--if you overshoot, you'll eventually drift back on your own. You may want to lower aggression to 90%, for smoother adjustments.
Play with the things I suggested *one* at a time. However, I don't think you have major guiding issues at this point. You *do* need to be careful with PA *every* time, and it would help if you used Sharpcap. Another thing you can eventually try is to measure and enable backlash compensation. Not sure it'll work well with the AVX, but it might with the iEQ45.
At this point you need to work on your calibration frames. And don't image when there are clouds, unless you are stuck babying the mount.
