3056 x 3056 pixels, 36.7 X 36.7mm chip. Suitable for all wide field applications. The reason I am selling it is that it’s too heavy to mount on my 20inch newtonian (f3.5), but would be perfect for an SCT or Astrograph on a fork or German equatorial mount with counterweights.
I bought it 2 months ago from Crni Vrh Observatory (MPC observatory code 106) who used it for their asteroid survey. It is in perfect working order and they gave it a full check up before shipping. The chamber was purged and refilled 2 years ago, so you won’t have problems with condensation or ice crystals. Apogee offer this as a lifetime free service anyway. You ship it to Andor in Belfast, they refill the chamber with argon gas, and send it back to you for free. I am asking £1480 which is what I paid for it 2 months ago.
The £20 shipping is for standard post which can take 3 weeks, but faster methods are available. The camera comes with power supply, USB cable, mounting plate, mounting adapter, and 3 spare fans. If you are not familiar with Apogee cameras, I posted the link to the S&T revue below. I have used them for 20 years and apart from replacing a fan occasionally, have never had a problem.
