Apogee Alta U47 CCD camera, with thinned back-illuminated CCD for high quantum efficiency and increased blue sensitivity. 

1000 x 1000 pixels, 13 micron.  Very high sensitivity with thinned back-illumined E2V CCD.  Quantum efficiency up to 90% across V and R.  Blue sensitivity around 45%.  This is a science-capable camera, used for photometry for years.  Original camera was an AP-47, with the chip transferred to an Alta U-series body several years ago.  Camera operating flawlessly.  Includes 1-1/4” IR cutoff filter to prevent fringing inherent with this type of chip.

Closing observatory due to age and infirmity of operator, not that of instrumentation.
