QHY Camera 268M Mono (83338)

The QHY Camera 268M Mono is a cooled monochrome astrophotography camera designed for high-sensitivity imaging of the Moon, planets, nebulae, and galaxies. It features a back-illuminated CMOS sensor, which allows more light to reach the photosensitive layer by positioning the wiring beneath it. This design increases quantum efficiency, making the camera especially effective for capturing faint astronomical objects. The camera is equipped with advanced cooling, high bit depth, and fast data transfer for deep-sky and planetary imaging.

Back-Illuminated CMOS Sensor
The back-illuminated structure enhances sensitivity by allowing more photons to be converted into electrons, improving performance in low-light conditions and increasing the camera’s ability to capture dim targets.
