GSO RC8 focuser issue ??
Where the focuser screws on to the scope or extension rings the flang (for want of a better word) on the inside edge of the focuser has a 45 degree bevel.
When you screw the focuser in i dont believe that it is sitting perfectly flush with the adjoining ring end. It moves around on the 45degree bevel.
I would imagine that in order to have a perpendicular plane to the mirror you would need the focuser flush.
I am considering lathing the focuser to ensure a flush fit.
has anyone else noticed this and does it cause tilt issues in the image?
Assistance please
Regards
Carl Rainer
