ToupTek GPM Series Guide Camera!
Professional autoguiding camera featuring Sony IMX662 STARVIS 2 sensor with exceptional infrared sensitivity for precise telescope tracking and versatile astronomical imaging. The GPM662C features Sony's cutting-edge STARVIS 2 back-illuminated sensor technology, delivering exceptional infrared sensitivity with a peak QE over 91%. The 2.9μm pixel size provides the perfect balance between resolution and light gathering capability for planetary imaging!
Sony IMX622 Color Sensor Technology
The GPM622C features Sony's IMX622 color back-illuminated sensor with exceptional infrared sensitivity. With read noise as low as 0.48e⁻, full well capacity of 39.03ke⁻, and dynamic range reaching 75.2dB, the GPM622C delivers outstanding performance for astronomical applications. The color sensor provides natural color reproduction while maintaining excellent sensitivity across the visible spectrum.
Exceptional Infrared Sensitivity
The GPM662C excels in capturing infrared light with remarkably high quantum efficiency at 650nm wavelength. This superior IR sensitivity makes it ideal for planetary imaging, revealing details invisible to standard cameras.
Built-in ST4 Autoguider Interface
The GPM622C 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
Hardware-based ROI increases frame rates for guide star tracking. Digital binning from 1x1 to 8x8 in both stacking and averaging modes. Integrated memory buffer ensures stable data transmission and effectively reduces amp-glow, maintaining consistent frame rates even with multiple cameras. The built-in ST4 port enables direct mount control for auto-guiding, making the GPM662C an ideal dual-purpose guide and imaging camera.
