- Fires up to 150 FPS at full 1080p HD resolution
- Reaches down to a razor-sharp 0.47 e- minimum paired with a peak quantum efficiency exceeding 92%
- AR (Anti-Reflection) protective glass to maximize light transmission
- Extended-length is specifically desgined for compatibility with Off-Axis Guiders (OAGs). The shorter flange distance provides more back-focus adjustment space, making it much easier to achieve focus across a broader range of OAG
ToupTek G3M Series Planetary Cameras
The planetary camera G3M2210M adopts SmartSens technology, making it ideal for astronomical photography, microscopy, industrial vision, and guiding applications. Featuring an extremely low readout noise down to 0.47 e-, high sensitivity, and a 12-bit ADC back-illuminated CMOS sensor, the G3M2210M delivers high-resolution monochrome astronomical images with exceptional structural detail and contrast. The camera also includes AR-window glass to optimize maximum photon capture across the visual spectrum for planetary, lunar, and solar imaging applications.




Sony STARVIS & Exmor R Technology
G3M178C features Sony's advanced STARVIS and Exmor R technologies, delivering exceptional low-light sensitivity and high image quality. The back-illuminated sensor structure maximizes light collection efficiency, achieving over 81% quantum efficiency. With a sensitivity of 425mv at 1/30s, this camera excels in capturing faint celestial details even under challenging conditions.


High-Speed Data Transfer
With USB 3.0 connectivity, G3M2210M delivers stable high-speed data transfer, achieving up to 150 FPS at full resolution in 12-bit mode. This high frame rate capability is essential for lucky imaging techniques, allowing you to capture hundreds or thousands of frames quickly to select and stack only the sharpest images affected least by atmospheric turbulence.


OAG Compatibility
The extended-length version supports OAGs from third-party brands ( when used with a guide camera). It's elongated design provides greater adjustable range while maintaining the original sensor flange distance.


Ultra-Low Noise Performance
G3M2210M achieves remarkably low read noise of just 0.47 e⁻ at high gain settings, ensuring clean images even when pushing the camera's sensitivity limits. This exceptional noise performance, combined with the high full well capacity of 8.5ke⁻, provides an impressive dynamic range of 68.5dB, allowing you to capture both bright planetary features and subtle atmospheric details in a single exposure.


Spectral Sensitivity
The G3M2210M sensor offers excellent spectral response across the visible spectrum from 380-690nm (with IR-cut filter). The optimized color filter array ensures accurate color reproduction while maintaining high sensitivity, making it ideal for capturing the subtle hues of planetary features and lunar landscapes.
