QHY294MPro
The QHY294M Pro is an impressive astronomy camera designed for astrophotography enthusiasts. Let’s delve into its features: Sensor and Resolution: The QHY294M Pro boasts a 4/3-inch back-illuminated sensor equipped with the Sony IMX492 (Mono) sensor. It offers two readout modes: Locked Mode: Produces 11.6 MP images with a pixel size of 4.63 μm and 14 bits per pixel. Unlocked Mode: Generates 46.8 MP images with a pixel size of 2.315 μm at 12 bits per pixel1. Dual Gain Mode: The camera features HGC (high gain) and LGC (low gain) modes. When the gain is set to 1600, it automatically switches between these modes. In HGC mode, you benefit from ultra-low read noise (1e- to 1.6e-) and a full well capacity of about 14.5 ke- at the switch point setting1. Back-Illuminated Sensor (BSI): The BSI structure improves full well capacity. Unlike front-illuminated sensors, where photons must pass through metal wiring before reaching the photosensitive layer, the back-illuminated senso
