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 × 2160 pixels. The camera features a cylindrical housing.
The pixels measure 2.9 µm. 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.
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.
The saturation capacity is 39.75 ke−. 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.
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.
The reported read noise ranges from 4.29 to 0.52 e−. 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.
The documented frame rate is 18.2 frames per second at 1920 × 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.
La ToupTek GPM585M est destinée à l'autoguidage : montée sur une petite lunette guide ou un diviseur optique, elle suit une étoile et envoie les corrections à la monture pendant les poses longues. Avec ses pixels de 2,9 µm, elle échantillonne à environ 4,7″ par pixel sur une lunette guide Askar 32 mm (128 mm de focale) et 2,9″ sur l'Askar 52 mm (208 mm). La lunette guide convient aux focales d'imagerie courtes à moyennes ; pour les longues focales, le diviseur optique est plus précis car il guide à travers l'instrument principal.
Le Sony IMX585 (technologie STARVIS 2) combine un très faible bruit de lecture (0,52 e⁻), une capacité de puits élevée pour des pixels de 2,9 µm (39,75 ke⁻) et une sensibilité marquée dans le proche infrarouge. Sans amp glow, c'est un capteur très polyvalent, du planétaire au ciel profond, avec un excellent rapport prix-performances.
No: It is powered by its USB cable. No external power source is required.
It slides into the 1.25″ eyepiece holder of a guide scope, such as the'Askar 32 mm or the'Askar 52 mm, or can be mounted on an optical splitter. The ST4 port allows corrections to be sent directly to the mount; when using a computer or an ASIAIR, guiding is most often done via USB.
