ToupTek G3CMOS178M Planetary Camera – Sony IMX178 Monochrome

The ToupTek G3CMOS178M is a high-performance air-cooled monochrome planetary camera built around the Sony IMX178 sensor. With its high resolution of 3096×2080 pixels and small 2.4 µm pixel size, the IMX178 is particularly well-suited for capturing fine planetary detail at moderate focal lengths, and also works well as a monochrome guide camera or for lunar surface imaging.

Who Is This Product Best For?

The G3CMOS178M is ideal for intermediate to advanced planetary imagers who want high-resolution monochrome planetary captures. It also functions well as a guide camera for precision autoguiding.

Why Choose This Product?

• Sony IMX178 Monochrome Sensor: 3096×2080 pixels, 2.4 µm pixel size — high resolution for fine planetary detail at moderate focal lengths.
• USB 3.0 High-Speed Interface: High frame rate capability for lucky imaging stacking workflows.
• Compact 1.25" Barrel Body: Integrates seamlessly with any standard focuser or Barlow lens.
• Versatile Use: Suitable for planetary imaging, lunar detail, solar imaging (with filter), and precision autoguiding.
• Compatible Software: Works with SharpCap, FireCapture, PHD2, NINA, and ASCOM/INDI drivers.

Recommended Uses

• High-resolution monochrome planetary and lunar imaging
• Solar imaging with a proper solar filter
• Precision autoguiding for astrophotography setups

Compatibility and Accessory Notes

• 1.25" barrel; fits standard focusers and Barlow lenses
• Monochrome sensor — use with planetary filter sets for colour results
• Compatible with INDI, ASCOM, SharpCap, FireCapture, and PHD2

Important Limitations

• Air-cooled only — not suited for deep sky long-exposure imaging
• Monochrome — requires planetary filter sets for colour planetary imaging

Frequently Asked Questions

Can this camera be used as a guide camera?
Yes — the G3CMOS178M works well as a guide camera with PHD2 and other guiding software via its ST4 or USB interface.

How does the IMX178 compare to the IMX174?
The IMX178 offers higher resolution (more pixels) with a smaller pixel size, making it better suited for capturing fine detail at shorter focal lengths. The IMX174 has somewhat larger pixels and better per-pixel sensitivity.

Our Recommendation

The ToupTek G3CMOS178M is a versatile monochrome camera for intermediate to advanced imagers who want high resolution for planetary detail capture and the flexibility to use it as a guide camera. An excellent value for its sensor quality and USB 3.0 performance.
