Fred I don't think the mirror can be raised or lowered. It seems fixed into position but there are three screws holding it down. These might be for tile and tip I guess.
The guide cam does not have to pull out to reach focus, it needs to go in to reach focus. Well to make it clear I had to wind down to move close to focus. When I was fully in I still had to move further in. If I put a spacer in this will just make the guide camera further away from focus? Isn't this right?
Kevin from QSI seemed to think mis-shapen stars are not a problem. What are your thoughts Fred?
