Subject: Focusing

I am new to the group, and have just ordered a ¼” chip imagining source color cam without IR cutoff (firewire) to connect up to my macbook using the Astro IIDC software I just downloaded. So I am trying to get oriented not having used anything but a DSLR in the past and focused for that using mechanical focusing aids (http://www.stellar-international.com/).

How does accurate focusing occur with these cameras and Astro IIDC? Do you mechanically focus your scope based on the image on the screen in the software? Or based on other indicators in the software? If by image that sounds like a challenge for solar imaging when the sun will be washing out good screen viewing even with covers. Is there a feedback loop from the software to control a motorized focuser for telescopes?

Sorry I do not know anything about this yet, just a newbie trying to understand how this works.
