Simple and effective.
Keep at it it Eric
I use the LCD screen on the camera despite the heat issues. I find the 10x zoom on the camera much better than going back and forward between laptop and camera to focus.
I don't know how long it takes to achieve sharp focus using software, but I know it is super quick with live view and my eye!
I don't understand why focusing with the 40D is a major concern for you Eric, and apart from that, don't the other features and specs make it very desirable as an astro DSLR?
Are you justifying a CCD purchase to yourself!!??
All the best whatever you do
