The QHY5III174M is an uncooled monochrome planetary and guide camera built around Sony IMX174. It records 1920*1200 pixels with 5.86μm*5.86μm sampling and 12bit (output as 16bit and 8bit) conversion/output.
QHY lists 32ke- full well and 2.2e- to 5.5e- read noise. The published full-frame rate is 138FPS@8bit. The global shutter exposes the image area simultaneously, making this camera useful for moving targets and short-exposure imaging.
The interface is 1.25-inch, with CS and C-Mount; the guide connection is Custom ST-4. Backfocus is 12mm. The AR window preserves broader wavelength transmission for external filter selection.
The camera uses USB3.0 Type-B for image transfer and power, with a published weight of 85g. This first-generation model uses a custom ST4 cable arrangement; use its matching guide cable.
