The C90 fluorite mystery

So here's something interesting that will be in my collection soon...

After a LONG search (decade + years) I have found and will be picking-up a mint conditioned 1985 Celestron Super Polaris C-90 Fluorite. This will have all the original whistles and goodies; even a like new and vintage MD-3 stepper motor drive set (like the ones on my SP-DX, but black).

Here's the mystery folks:

In my 1985 Orion catalog, it says the C90 is a "high-precision triplet fluorite system." Uhh..Errr..What?! I though ALL Vixen fluorite scopes were doublets; a Canon-Optron fluorite in the rear and a (German-sourced) crown flint front.

Is this a typo on Orion's part or is the black-tubed C90 fluorite a true triplet system?


The 400 mile drive to get the SP-C90F commences the 2nd week of April.


Best all!
