Wow, I did not know that Celestron ever made such a thing.  Very handy for aligning guide scope with main scope.  I have a similar device from Astromania, but it doesn't look

quite as sturdy as that one.   Works quite well, though.  Very handy.

I have a similar one on a 1976 C5 that is drilled for a 8 inch Schmidt camera.

Your tangent-to-main scope mounting holes look like they may be the same.

Yours is a later tangent with a single 1/4"-20 screw that I'm pretty sure uses

this bracket shown:

Here's the early version with it's connections for a C5.

On the main scope side of the tangent the wide spaced arrows are 8 inch Schmidt

camera and possibly others.The narrow spaced arrows are C14.

I was going to modify mine to fit my C14 but chickened out due to two reasons,I

didn't want to do irreversible modification, although it didn't matter because

Celestron did exactly the same thing, and I felt strongly I'd someday own a

8 inch camera.

I sold the C14 and I would like to own a 8 inch camera someday. And although

these days there are many modern choices for guiding I still think I would like

to do it with a C5 guide scope, exposure times will be very short.

I had one years ago for a C5 and my C14.  Paid heavy price for it back in the 90's.

I picked up an orange tube C-5 guide scope with tangent assembly last year.

They don't pop up for sale very much. Avg price for one back in the 90's was over $200.

I have had a couple of those and I paid dearly for them a couple of years ago and then I sold them with some scopes.   They were a coveted item with the blue and white celestrons.  The 4" and 5" blue and white guide scopes were always mounted on the blue and white celestrons with those tangent arms. However, they were painted blue in those days.
