Yes - in most cases, as per the RCOS website. I guess I was talking more generally (or vaguely) about how the Ritchey optics behave during alignment and within the frame of a telescope - not so much the solution.
Do you use the tak scope Ken?. Not suitable for reflectors with a relay lens according to Takahashi. I have a Tak scope on backorder however (and use CCDAP/stack/inspector) The tak scope requires a precise centre mark for the secondary mirror - not sure if the new GSO RCs have such a mark?
