ToupTek G3CMOS294 Planetary Camera – Sony IMX294 Colour

The ToupTek G3CMOS294 is a large-format air-cooled colour planetary camera built around the Sony IMX294 sensor. With its large 4144×2822 pixel array and excellent sensitivity, the G3CMOS294 delivers outstanding one-shot colour performance for high-resolution planetary imaging and can also capture faint solar system detail for targets that benefit from a wider field of view.

Who Is This Product Best For?

The G3CMOS294 is well suited for intermediate to advanced imagers who want a large-format colour camera for planetary, lunar, and bright comet imaging. The large sensor format provides a wider field that works well for wide planetary conjunctions and extended targets.

Why Choose This Product?

• Sony IMX294 Large Format Colour Sensor: Wide dynamic range, good sensitivity, and a large field of view for planetary and bright target imaging.
• USB 3.0 High-Speed Interface: Supports high frame rates for lucky imaging workflows.
• One-Shot Colour: Natural colour without the need for separate filter sets.
• Compact 1.25" or C-Mount Body: Flexible integration with focusers and Barlow lenses.
• Compatible Software: SharpCap, FireCapture, NINA, and ASCOM/INDI.

Recommended Uses

• High-resolution colour planetary and lunar imaging
• Wide-field solar system target imaging
• Bright comet and extended target imaging

Compatibility and Accessory Notes

• Compatible with standard focusers and Barlow lenses
• Compatible with INDI, ASCOM, SharpCap, and FireCapture

Important Limitations

• Air-cooled only — not suitable for deep sky long-exposure imaging
• Colour Bayer sensor — less sensitive per pixel than monochrome variants

Frequently Asked Questions

Is the large sensor useful for planetary imaging?
The large sensor provides more context around planetary targets and works well for wide planetary groupings, extended solar system objects, and bright comets where a larger field of view is an advantage.

Can I use this for deep sky?
This camera is not optimized for long-exposure deep sky imaging. For that purpose, consider the ToupTek ATR294C cooled camera.

Our Recommendation

The ToupTek G3CMOS294 is a capable large-format colour planetary camera for intermediate to advanced imagers who want a wide colour field for solar system targets. An excellent choice where a wider field of view provides a distinct imaging advantage.
