ToupTek ATR183C Deep Sky Cooled Camera – Sony IMX183 Colour 20MP

The ToupTek ATR183C is a professional one-shot colour deep sky cooled camera built around the Sony IMX183 high-resolution full-frame adjacent sensor. The IMX183 delivers 20.3 megapixels of colour imaging capability, making it well-suited for high-resolution widefield deep sky imaging and multi-panel mosaic projects.

Who Is This Product Best For?

The ATR183C is ideal for intermediate to advanced astrophotographers who want high-resolution colour imaging capability with the convenience of a one-shot colour workflow. It excels for widefield imaging, mosaics, and capturing extended nebular structures with natural colour detail.

Why Choose This Product?

• Sony IMX183 20.3 MP Colour Sensor: High resolution for detailed widefield imaging and mosaic panels.
• Dual-Stage TEC Cooling: Up to 45°C below ambient with ±0.1°C precision temperature control.
• Anti-Dew Window Heater: Four-level adjustable heating for reliable all-weather imaging.
• 512 MB DDR3 Buffer + USB 3.0 5 Gbps: Stable high-speed transmission for large image files.
• Up to 1-Hour Exposures: Captures faint detail in extended deep sky objects.
• HCG/LCG/HDR Multi-Mode Support: Adaptive gain modes for different imaging scenarios.

Recommended Uses

• High-resolution one-shot colour widefield astrophotography
• Multi-panel mosaic imaging of large nebulae and galaxy groups
• Colour imaging of star clusters and star-forming regions

Compatibility and Accessory Notes

• Requires external 12V 3A DC power supply or stable 11–14V lithium battery
• Compatible with ToupTek OAG-L, OAG-X, AFW-L, and StellaVita controller
• M42 thread connection standard

Frequently Asked Questions

Is the ATR183C suitable for imaging with a refractor?
Yes — it pairs well with wide-field APO refractors. A flattener/reducer is recommended for best edge-of-frame performance.

What is the best application for 20MP imaging?
Multi-panel mosaic projects and widefield imaging of large extended nebulae benefit most from the high pixel count of the IMX183.

Our Recommendation

The ToupTek ATR183C is an excellent high-resolution one-shot colour camera for serious astrophotographers who want to image wide fields with natural colour and fine detail. It is particularly well-suited for widefield nebula imaging and ambitious mosaic projects.
