Selling my SCT crayford focuser in excellent condition. It was purchased for my C9.25 SCT and fits it perfectly. It's a lovely unit. Comes in original carton. It's spent 99% of its life inside my house unused since new, so it's time to move it along. Note that it doesn't come with the 2" to 1.25" eyepiece adaptor.
Bintel has these listed for $219 just now with no stock.
$130 shipped Australia wide with Direct Freight Express (no PO Boxes please).
I'm not 100% sure. I'd say I'm 99% sure that the C8 and C9.25 both share the same rear thread size though. Looking at Celestron's website it looks like they're the same:
