SBIG ST2000 XCM for sale.

Works fine. We don't image at night so much - mostly daytime imaging.

Includes a good older copy of CCD soft, a 1.25" drawtube to female T-thread adapter, the relay adapter box, pelican case and has the jackets for water cooling heat exchanger.

Bought in 2005. The attached image of Pluto was taken that summer on a 22" dobsonian while down in Bolivia. (we pushed the mirror really far up to reach focus using the focus screws).

We pay shipping within continental US.
