The mirror is marked f5.6, but I had to mount the mirror about an inch closer to the secondary than what I had calculated in order to be able to focus a 55mm lens with the focuser racked almost all of the way out. I am able to rack the focuser most of the way in and focus an 8mm eyepiece. I think there is a little over 2 1/2 inch travel on the focuser.
