Re: Slewing/GoTo works, poor tracking and guiding

Just one thought... how’s the weather when you were trying to guide? 15” error probably says that there’s something wrong mechanically.

You really need to provide more information instead of just declaring the mount “sucks”.

What do the guide pulses look like?
Is the mount even responding to guide pulses?
What interface are you using for guiding? If it’s ST4, maybe you have a bad connection (hint: don’t use ST4!!!)
Do the guide rates in PHD2 and Onstep match? Have you tried disconnecting the motor and rotating the worm by hand?
Backlash in RA should not affect the guiding too much, since you’re practically going in 1 direction only.
