These QHY Cooled CCD's were all the rage back in their day & still their performance are rated very highly.

This camera has not seen a great deal of work and I would estimate between 20 & 30 nights over the 5yrs I've had since new, which it has performed flawlessly.
As with most my gear, this Camera has never been opened, not even the desiccant chamber as they are very well sealed in production, so why open it unless there is a good reason.
It has seen a few sub zero nights out west in mid winter, these cameras are design for much more xtreme conditions than a measly -5 & has never seen any condensation due to being in my Observatory out there.
It is in very good condition, easily last another 5-10yrs in the right hands.
I am going to ask
