The ToupTek Astro GPM585M is a high-sensitivity monochrome astronomical camera designed for guiding deep-sky exposures and infrared imaging. Its 1\/1.2-inch Sony IMX585 Mono sensor offers a resolution of 3840 \u00d7 2160 pixels. The camera features a cylindrical housing.<\/p>\n

Sensor and Sensitivity<\/h3>\n

The pixels measure 2.9 \u00b5m. When used for guiding, the pixel size affects the sampling, while the sensor format affects the field of view. These parameters must be considered in relation to the focal length of the guiding optics.<\/p>\n

The reported peak quantum efficiency exceeds 91 %. Quantum efficiency describes the proportion of incident photons converted into an electronic signal. A peak value characterizes the maximum of this response; it does not describe uniform efficiency across all wavelengths. ToupTek also intends this model for infrared imaging.<\/p>\n

Signal, Readout Noise, and HDR<\/h3>\n

The saturation capacity is 39.75 ke\u2212. It indicates the amount of signal a pixel can accumulate before saturation. This limit affects the recording of bright areas: a saturated pixel no longer preserves intensity differences beyond its capacity.<\/p>\n

The analog-to-digital conversion is rated at 12 bits, with 16-bit operation in HDR mode. ToupTek reports a dynamic range of 88.09 dB in this mode. Dynamic range describes the difference between the weakest and strongest signals that can be recorded; the published value specifically refers to HDR.<\/p>\n

The reported read noise ranges from 4.29 to 0.52 e\u2212. The reported minimum value represents one end of this range, but is not presented as a constant value. The reported maximum signal-to-noise ratio is 44 dB; it characterizes the ratio between the signal and the accompanying noise.<\/p>\n

Acquisition rate<\/h3>\n

The documented frame rate is 18.2 frames per second at 1920 \u00d7 1080 pixels in 8-bit color. This frame rate is documented for this setting; the announcement does not specify any frame rates at full resolution or in HDR mode. The transfer interface uses a Type-C connector over a USB 2.0 connection.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"
