Sensor information

Other cameras in the same sensor family (5)

Sensor-family links do not mean the complete cameras have identical spectral responses.

Source and sensor identification

Celestron product page names the 678C camera with Sony IMX678-AAQR1 color back-illuminated sensor. This shares the IMX678 sensor identity with DWARF 3 telephoto and other cameras when color variant matches; camera-body responses remain distinct.
