Thanks for the feedback Robin. Re the F Stop. I actually shot this using the Canon piggbacked on the scope. Isn't F5.6 a wider (more open) aperture than F10 - so would require less exposure rather than more?
I suppose the other thing I still can't resolve is that the other chap I linked to used the same settings that I did, yet got a drastically better result.
Anyway, I'll keep pushing along .. lots to learn!
Cheers
David
