Megrez - Doublet or Triplet best for imaging?

Hi All,

This is a question on behalf of a friend who has just moved to Oz (lucky
chap) and who doesn't have internet access yet.

He want's to buy a 80mm refractor, mainly for imaging, and he currently uses
a 350D as his prime imager, although he may make the move into a smaller
chip astronomical CCD camera at some time in the future.

He likes the build quality and price of the Williams Optics Megrz scopes,
and his budget would allow him to buy either the Flourite doublet, or the
"non-flourite" triplet models with only £40 difference between them.

His question is simply which model would be best suited for his imaging
requirements?

I can't help him as my only 80mm refractor experience is with the 80ED and
BC&F Revelation 80 "Apo", both of which are doublet designs, and appear to
have excellent colour correction to me when observing the Moon and bright
planets, etc. I've no experience with triplet designs, although the
marketing blurb from Meade for their new 80mm triplet would have us believe
any triplet is superior to any doublet design.

Your collective experience, observations and advice would be very much
appreciated.


Many thanks and clear, dark skies.
