2) I shown a flashlight through the polar scope port of my CGEM DX. It's wide illumination filled the port, and illuminated a point on the dome that is presumably within 1 degree of north. No amount of flashlight tipping would move the spot (it isn't a laser, it is a broad; see the attached picture named DefiningNorth). I defined the positioning of the dome to be at 0 degrees when the spot was centered on the shutter.
