Application context

Why this design is used

Choose the G3M715C when 47 fps acquisition, 1.45 µm sampling and the IMX715 sensor match your telescope's focal length and seeing conditions.

Planetary lucky imaging

47 fps capture supports frame selection and stacking for Jupiter, Saturn, Mars and Venus.

Lunar surface imaging

1.45 µm pixels and 8.3 MP (3840 × 2160) resolution support detailed lunar mosaics and close-up imaging.

One-shot colour planetary imaging

The colour IMX715 sensor provides a direct RGB workflow for planets and the Moon.

Solar imaging with approved filtration

Can be used for solar capture only with an appropriate certified solar filter and safe observing setup.

Integration and compatibility

Use these checks to connect G3M715C 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 IMX715 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: 47 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: 72.8 dB · Read Noise: 1.35–0.57 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.

Technical FAQ

Integration questions for G3M715C

What lens mount is required for the G3M715C?

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.

What sensor and pixel pitch does the G3M715C use?

Sensor: Sony IMX715 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.

How does the G3M715C connect to the acquisition computer?

Frame Rate: 47 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.

What is the noise performance of the G3M715C?

Dynamic Range: 72.8 dB · Read Noise: 1.35–0.57 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.
