3200 megapixels custom CCD array cooled to about -100 °C sounds amazing.

The 3.5 degree FoV is around 700 mm focal length equivalent on a full frame camera which makes this relatively wide field by telescope standards, allowing it to capture more of the sky per shot. But the array is 64 cm wide so the actual focal length is around 10 meters.
