NARIT CCD Cameras

I assisted the National Astronomical Research Institute of Thailand with the construction of two CCD cameras in their Chiang Mai headquarters.

The first was a warm CCD4720 1Mpix camera intended to gain experience with the Archon controller.

The second used the same CCD but in a liquid nitrogen cooled cryostat.
