I found it at http://www.highpoint...n-C8-A-SCT-A... . They are selling a Nexstar C8 SE OTA and the C8A (URL above).
My old 1980 orange tube blew over at Okie- Tex last Sep. it seems OK but I think I might need to replace it. Views of Jupiter at higher power are fuzzy but I'm not really sure that's not collimation. So I'll see on the next clear night if the problem is collimation and if not I'll probably get a new OTA.

This just the old nomenclature where you had C8-A and C8-CF.
A = Aluminum Tube
CF = Carbon Fiber Tube
My C11 was called a C11-CF when I bought it.

The black tube has the dovetail bar on the bottom (relative to the finder).
The orange tube (probably)has a black dovetail bar.
The black tube has an orange dovetail bar.

The hazzard of relying upon memory rather than looking at an image of the SE.
I think relative to the focuser you'll find the dovetail bar is in the same position.
The embarassing part is big clue I might have seen if I'd looked at my C5 first.

I hadn't heard of a C8A?
