@LaserMan I seriously doubt this would be sensitive enough for southern hemisphere.

NEQ6 and HEQ5 mounts have a red led polar scope illumination.

How do you get the red background to the view....I went out last night and tried it out and Polaris was on the screen but the diagrams were invisible because it was dark out....what did you do to get a red background?
Microsoft lifecam cinema works ;)
A couple of years down the line these Philips webcams have started to get sought-after and so quite expensive because people like to use them for entry-level CCD imaging, so it might be an idea to recommend a cheap and cheerful CMOS webcam to use as a dedicated polar alignment aid. Something that can pick up Polaris and maybe the dimmer Octans stars, but would be so-so as an imager. Any ideas?
Orientation is irrelevant, if polaris is in the small circle it doesn't matter which way the camera is rotated, it's still in the circle. 
@michaelgossage You can, if you want, open it up and kill the led, to be honest, I haven't on mine and it has no detrimental effect to performance, but the easy way would be to just put either a piece of tape over it or paint it with nail polish.
