Re: Error Message

Re: Guiding pains
yes, problem happens with and without the dark frame, I mean when you select the pixel and do it manually that shouldn't matter at all anyway except for enhanced centroiding... but really even that should be robust to pixel errors.

Having said that I have an easier time with the guide scope vs the celestron oag in f/7 and f/10 because we're talking about ~2000-3000mm ...

Re: Guiding pains
I'm still reliably having issues with guiding, the calibration step in particular. It seems like it's either related to having a fresh telescope connection or whether or not I have my main zwo camera connected. I've only been able to track it down to those 2 sensitivities. It seems like it breaks th...
