Actually there's a bunch of different 60mm Celestrons.
Orange, Black, Blue/Gray available in Alt-Az and GEM with too many variations to say or keep track of.
Probably the most common was the blue/gray alt-az Cometron CO-60, but even some of those came on a Polaris mount (CO-60E).
Here's my Vixen made C60 (OTA only), on a Unitron mount and it might just be the best 60mm I have.
This model came standard with a 1.25" visual back. A .965" VB is on it in this photo
because eye pieces and diagonals were being swapped with other scopes during a shoot out.
I had no idea that Vixen made any of the C60s or that some came with Polaris mounts. Yours is a very nice example. Mine is black with a plastic .965 focuser on a yoke mount. KD emblem on the underside of the focuser.
