Hi all,

I have been recently trying to get my guiding better. I have a Celestron 8" EdgeHD + 0.7x reducer and an AVX mount.

This is my startup routine:
- Run the AVX two star align + 4 calib stars
- Run the AVX polar align
- Open PHD2 and run the calibration routine
- Run the PHD2 drift align (but the AVX polar align did the trick this time)
- Run the PHD2 guiding assistant to work out the best settings

This is the first time i have done this and my guiding improved a lot. I was consistently under 1 RMS error.

3 questions:
- The first picture is my backlash graph from the Guiding Assistant routine. Does this look right?
- The first guiding graph is around the zenith. When i was doing this i was getting 6 min exposures with no star trails. The second graph was near the polar star. The graph looks better, with lower error, but each time i tried to do a 6 min exposure i was getting noticeable star trails. Why is this and how do i remove this error?
- Any tips on my guiding based on the graphs in general?

Any tips appreciated.
Cheers, Boz.
