Thanks for a most informative review Mick; just the sort of thing I've been looking for as a refractor around this size has been on the "wish list" for some time now.
Initially I was considering an 80 mm WO ZS FD but came to the conclusion that its 555 mm FL would not deliver the "bang" needed for planetary work.
Had to dismiss all thought of APO refractors of 100 mm and over on cost basis; the proposed Meade 127 might change that one though.
That left achros and 100 mm EDs. No one in either of my two astro clubs has one of the latter, so I'm left wondering whether they would pass the "bang-for-buck" test.
If you wouldn't mind a couple of queries:
Did you ever try a "minus violet" filter and if so, how did you find it?
Did you find viewing near zenith difficult? The eyepiece seems rather low in the picture.
Once again, thanks for your efforts.
Mark.
