Nope - no luck
I tried a different camera - an ST10-XME this time. It has a different nosepiece yet suffered from the same aberration when rotated. So its not the camera or nosepiece
I'm at my wits end. All looks quite good in the Tak collimation scope but the stars are still distorted.
Perhaps its the spacing between primary and secondary - anyone know how to measure this on a RC8?
