I’d appreciate any hints or suggestions from users of the ZWO 30F4 guidescope. I have just begun using this and have the ZWO ASI120mm camera. I think this is a common popular combination. I have had several good evenings using this with PHD2. But two nagging problems remain.
1. To focus the camera with supplied extension tube, the camera is pulled out nearly all the way and so is “only just” mounted into the back of the scope. It works ok but I wonder why it only just fits, why would they design it that way? I assume I am doing something wrong.
2. Turing the black focusing tube at the front of the guidescope gives a very fine adjustment - , several rotations seems to have only a marginal impact on focus. But when I tighten the red lock ring, it goes out of focus. So currently guiding without the lock engaged. Again may I am doing something wrong, or maybe the mechanism is broken?
any advice would be very much appreciated
thanks
