The QHY5III585C is an uncooled colour planetary and guide camera built around Sony IMX585. It records 3856*2180 pixels with 2.9μm*2.9μm sampling and 12-bit (output as 16-bit and 8-bit) conversion/output.
QHY lists 52ke- full well and 0.77e- to 8e- read noise. The published full-frame rate is 41.5FPS@8bit 23.5FPS @16bit. Region-of-interest capture raises frame rate by reading fewer sensor lines. The 512 MB DDR3 buffer reduces transfer pressure during high-speed recording.
The interface is 1.25-inch, with CS and C-Mount; the guide connection is Standard ST-4 Style. Backfocus is 17mm (with adapter);; 8mm（without adapter）. The IR-cut window suppresses infrared light during colour capture.
The camera uses USB3.0 Type-C for image transfer and power, with a published weight of 90g. The second-generation design uses USB Type-C, a standard ST4-style guide connection and a status indicator. Use QHY’s recommended data cable.
