After several adjustments with the original stock high precision worm (no OPWB) the best I could get was approximately 11 peak to peak.
After more adjustments to try and achieve better PE it was difficult for me to get back to this number. More frequently I was around 13-14 peak to peak.

So after much thought and hand-wringing I decided to go with Ovision. After a few initial adjustments this is what I got.

I think I can get even better with a few more adjustments but I'm not sure where to start. Can someone help interpret this graph so I know where to start?

Why bother? Looks good enough at +/- 3 Arcseconds. Maybe you can just train your PEC

I thought about that. But in looking at the frequency spectrum it just seems a little "noisey". I need to try with guiding next to see how far it gets reduced; then with PEC.

In looking at this I think the 32 second error is from the gearbox. At least I read that in another thread...that 32 second was the gearbox. For me thats about 1.2PE of error.
I guess I could switch the gearboxes on DEC and RA and see what it gives me.?

How do I interpret what the other are, like the 2nd 3rd and 4th harmonics? What do they correlate to?
Here is a better defined graph with PE.

Actually I found the answer here. Just had to read further.
