All you have to make sure really is that you kept the orientation of the secondary vis a vis corrector and primary and you'll be ok.

Hi Marc
Thanks for your comments. The orientation of the corrector is not a problem as there are engraved marks on the corrector (3 o'clock is the orientation of my Corrector). The orientation of my secondary is problematical, as it is rotated and I'm not sure by how much. I did read on Cloudy Nights that the mark on the secondary lines up with the Corrector marking, and my secondary does have a mark on it. I'm not sure whether this is Chinese whispers or fact, but it is a starting point.
Cheers
Peter
