You mention the focus, this is the imaging scope focus, or the guidescope?
Always having something to muck with seems to be part of the ritual.
The focus for the guidescope is easy as the eyepiece is parfocal with the videocamera in the flip mirror. The videocamera gives instant focus and position feedback on the LCD screen of the TVGuider.
Im now working on getting reliable and computer free focusing of a DSLR using a swap out system between the camera and a parfocal ronchi screen. I have had a go at this previously and it does work very well but I have to use a PC to get very accurate or best DSLR focus and then confirm this with a ronchi eyepiece. When I have this down pat I'll write it up.
I'm striving for accurate guiding and focus in the field, in the dark and without using a computer - and finally it has to be idiot proof (thats the hard part).
