Greetings - I am trying to get autofocus down and have used a bhatinov mask to get what it shows is good focus but my HFR is still above 2. Is this normal? I have recently replaced my stock focuser with a new Moonlite and the autofocus routine runs properly (decent V curve).
I am wondering if I have a collimation issue or something.
I am using an orion ED80/
