Selling my working Apogee Alta U32 CCD camera.  I'm finding out that I don't have the time to dedicate to mono imaging any more.
I've attached screenshots of recent Bias and Dark (600 sec) frames taken at -25C.  The camera cools very nicely to that temperature.  You can see a slight column defect on the very righthand side of the frame, but it calibrates out without any trouble.  The chamber was recently Argon purged and the desiccant swapped out.
A couple of notes from my personal experience:
* It is super sensitive - more so than some of the current mono CMOS cameras. 
* The KAF-3200ME is a linear CCD and does not have the anti-blooming gate.  Very high QE, great for actual science, but you can get blooming on bright stars pretty easily.
* It's built like a tank - very solid.  Make sure your setup can handle the 3.1lbs 🙂
Any questions, please ask.  Thanks for looking!
