I have got myself in a bit of a mess. I was trying to mount my starwatcher startravel 102 on a Vixen Porta II. I found that my scope dovetail is upside down (the dimples for the screws are in wrong place). Anyway, I tried to unscrew the dovetail and then turn it around. Unfortunately the two screws just keep turning and will not come out. I assumed that there would be a locking nut on the inside of the tube, seems not to be the case. I am now at a loss as to what to do, the screws will not tighten back up either. Any help would be greatly appreciated.
Thanks
Brian
