My Orion 10" dob lost a nut on the inside of the ota that holds one of the bolts in place on the altitude mechanism. This bolt is pretty much exactly halway down the tube...how am I supposed to fix this? I'm very hesitant about yanking the primary or secondary mirror off but I guess I'm going to have to. How hard is going to be to collimate the primary if I pull it? Thanks
