Application context
Why this design is used
Choose the G3M662C when 107 fps acquisition, 2.9 µm sampling and the IMX662 sensor match your telescope's focal length and seeing conditions.
Lunar surface imaging
2.9 µm pixels and 2.1 MP (1920 × 1080) resolution support detailed lunar mosaics and close-up imaging.
One-shot colour planetary imaging
The colour IMX662 sensor provides a direct RGB workflow for planets and the Moon.
High-speed solar and occultation capture
Fast acquisition supports brief events and solar imaging when the telescope uses a correctly specified solar filter.

System integration
Integration and compatibility
Use these checks to connect G3M662C to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Lens and microscope interface
- Mount: 1.25-inch telescope nosepiece / C-mount
- Use a lens image circle that covers the sensor and check flange distance before adding C/CS, F-mount or M42 adapters.
- Sensor and sampling
- Sensor: Sony IMX662 color CMOS · Sensor Type: STARVIS 2 back-illuminated color CMOS
- Match pixel pitch to the diffraction-limited spot the optics deliver. Sampling finer than the optics resolve multiplies data volume without adding information; sampling coarser discards resolution you have paid for.
- Interface and data rate
- Frame Rate: 107 fps · Interface: USB 3.0
- Confirm the host can sustain the interface bandwidth continuously, not in burst. A camera that outruns the write path stalls acquisition rather than dropping quietly to a lower rate.
- Cooling and noise floor
- Dynamic Range: 77 dB · Read Noise: 5.35–0.46 e⁻
- Judge these figures at the exposure time you will actually use. Cooling matters where dark current accumulates over seconds; read noise dominates short exposures where it never does.
