The AC378 model seems like the one I have (Mogg type) and the flange limits how far the webcam can be "pushed" into the focusser.
The AC624 has this retaning flange removed, so at least in theory should allow the webcam to move in closer to focus. This might be a solution for the PST users???
Anyone tried one???
