hi all
I was wondering if any one can throw some wood into the fire with this issue I am having .
I have a GSO 10" Truss F4 newt I have fitted a Moonlite focuser to it its a great scope for imaging but last night i noticed when collimating with my Hotech SC
collimator when i move the scope after getting the laser spot on the laser dot would move out of the centre dot on the main mirror then I would move it back to the position that I did the collimation in and it would be centred again
this is telling me that when I move the scope to different areas of the sky it will be out of collimation .
I have checked that every thing is tight but it has me puzzled
any suggestions ??
cheers Pete
