A good question Bruce.  I would say you may need to sorten slightly.  After
I
mounted my diagonal/image iinverter with the eye peice all the way in I
am barely in focus.  Unlike you I didn't consider the effects such a device
would have. I have always meant to fix that but never seem to get around
to doing so.  I really don"t know if thats why mine is off or I just messed
up
on the original calculation.  Okey panal, lets hear from the experts.
