So that is one thing i will fix,
Calibration steps is slightly different, but this can be from different mounts, mine is sitting at 812 while yours is at 900

So some good things there to try out.
Will have to watch that video also.

Appreciated.
When you change your guide scope focal length, you / PHD2 will have to calculate the calibration step again and therefore you will have to do a new calibration
Calibration is best done at Dec =0 or near the junction of the celestial equator and just before the north meridian ( in that area )
Your probably aware of this but I thought to mention it again as it catches a lot of folk out

Hope you resolve your guide Star issues

Also I use a 2 sec exposure which I’ve used for years under all conditions, some folk say it should be 1.5 to 1.0 under good conditions but I just leave it at 2 sec and it’s worked well for both my rigs

Cheers
