[NOT REQUIRED] Refractor Crayford 10:1 Dual Focuser SW 6"

[gavcol (G)]

Hi

I am looking for a good condition dual 10:1 focuser for my Skywatcher 150mm 6" Achromatic Refractor.

I am not sure what the tube OD is, I think it is 112mm from memory. I will measure and post later.

I was looking at GSO type variants.

Anyone?

Cheers

Gavin
