Dsi rc10c
If any has one of these, could you do a quick test for me please? If I pull gently on the focuser end cap, the one with the DSI logo, model and serial numbers, mine moves back and forth about a millimetre (along the optical axis) and I'm not sure if this is normal or if I have a lot of focuser backlash. If the latter, some idea of how to fix would be greatly appreciated.
Thanks,
Charles
