GSO 12" RC Truss Secondary Mirror collimation screws
I have just received the GSO 12" RC Truss and checked the collimation and it is very close, the laser falls inside the circle on the centre of the secondary but is just off to the side of the circle a fraction and probably doesn't need to be adjusted.
In attempting to loosen the screws to move the secondary, I cannot get them to budge at all. It is like they have been given a dose of Loctite at the factory. So far I have just tried the allen key and hand pressure to try and loosen it. My next option is possibly trying something on the end of the allen key to try and give some more leverage but I don't want to use too much force in case something I don't want to move, moves.
Has anyone been able to get these screws loosened and if so how? Now I understand why it held its collimation so well, there's no chance of them moving in transit.
I can't test the collimation with an image as I need to get another set of the M117 extension rings to even bring the CCD close to focus. Does anyone know if these are readily available in Australia or if they have to be ordered?
