Tak FS 76??

My local dealer has a used Tak FS 76 for sale. It is a fluorite doublet with a 600 mm FL. I am familiar with the FS 78 and have heard about the older FC76, but I have no info on a FS 76. Is this a very old scope, a rare scope, or did I somehow read it wrong? I am sure about the 600mm FL and the fluorite doublet, but I might have misread the label (but don't really think I did)!

Does anyone have any info on a Tak FS 76? How old is this scope?
How might it compare in performance to more modern 80mm doublets, etc.

Thanks for the help!

Gordon,

You might want to go back and take a closer look at the scopes ID plate because something is odd. You might have mis took (although you are confident you didn't) an '8' for a '6' and the scope may actually be an FS-78.

As far as I know the FC line, which had the uncoated Fluorite element at the rear of the cell, had the following apertures: FC-50, FC-60, FC-65, FC-76, FC-100 and FC-125.

Then Takahashi got more technically advanced and installed the now coated Fuorite element at the front of the lens cell and released scopes in the FS line with the following apertures: FS-60C, FS-78, FS-102, FS-128 and FS-152.

I never have heard of a FS-76 but then I might be wrong and that wouldn't be the first time. Please let us all know what you find out because from what you describe the FL (600mm) sounds about right. The FC & FS line were f/8 scopes.
