Bruce, You wrote "...and I imagine that is about the best I can expect with an a-12. I am trying to find a gentle way to clamp it to a tripod to lessen the human error a bit. There is a boss just behind where the bubble chamber plugs in. In mine it is tapped 1/4 inch Whit. and my camera tripod can be used to support the instrument using it. I think it was put there to hold it when collimating.
