ToupTek GPM Series Guide Camera!
A professional color guide camera featuring Sony IMX462 back-illuminated CMOS sensor, offering exceptionally strong infrared light capture capability with high QE value at 500nm, large full well capacity, high dynamic range, high sensitivity, and low readout noise for outstanding performance in planetary, solar, and lunar photography. The GPM462C camera possesses an exceptionally strong capability to capture infrared light with high QE values at 500nm. It features a large full well capacity, high dynamic range, high sensitivity, and low readout noise among other advantages. Equipped with HCG/LCG dual gain mode switching, the minimum read noise can reach 0.76e⁻. This results in outstanding performance in planetary photography, as well as in solar and lunar photography!
Sony IMX462 Color Sensor Technology
The GPM462C features Sony's IMX462 color back-illuminated sensor with exceptional infrared sensitivity. With read noise as low as 0.76e⁻, full well capacity of 12.7ke⁻, and dynamic range reaching 74.1dB, the GPM462C delivers outstanding performance for astronomical applications. The color sensor provides natural color reproduction while maintaining excellent sensitivity across the visible spectrum.
Sony IMX462 Spectral Sensitivity
The GPM462C sensor has a G sensitivity of 2376mv at 1/30s. Its spectral response range covers 380-690nm (with IR cut window), delivering excellent sensitivity across the visible spectrum. The sensitivity is measured with a testing standard lens with CM500S (t = 1.0mm) as an IR-cut filter and image at F5.6.
Built-in ST4 Autoguider Interface
The GPM462C features a built-in standard ST4 autoguider port for easy connection to the autoguider. This design simplifies guiding system configuration, reduces cable connections, and improves system reliability. Compatible with mainstream guiding software like PHD Guiding, MetaGuide, Nebulosity, MaxIm DL, and others for precise autoguiding control.
Comprehensive Connection Options
The GPM series cameras offer versatile connection options designed for seamless integration with various telescope setups and guiding systems. The diagram below illustrates the complete connection architecture, showing how the camera interfaces with your mount, computer, and other astronomical equipment for optimal guiding performance.
12-bit ADC and Intelligent ROI
The GPM462C features native 12-bit ADC, providing 4096 gray levels for capturing subtle tonal gradations and color information. The camera supports hardware ROI (Region of Interest) functionality - smaller ROI sizes achieve higher frame rates, which is particularly useful in guiding applications where only a small area containing the guide star needs high-speed acquisition.
