I'm looking for a step by step autoguiding primer of sorts. I have Milton's instructions of

course but I got stuck at calibration. Will likely get stuck again so I thought I would ask.

Hoping there is something out there that can get me unstuck - even if it is not written

specifically for Astro II DC. Perhaps a guide with some general principles of autoguiding

that have been helpful to folks using Astro IIDC.

Can you clarify what you mean by "but I got stuck at calibration"?

As to a general guide, here is two links to lists of things to check before attempting guiding.

The first is by Darryl Robertson creator Equinox and is on the Equinox list:

and the second link is some additions I added that are more Astro IIDC specific:

Points 12, 13 and 14 from my list are very important, as is having good polar alignment.
