1-Inch Back-Illuminated Sensor with 2.4 μm Pixels

The Sony IMX183 back-illuminated monochrome sensor delivers 20MP resolution with 2.4 μm square pixels, offering a strong balance of fine detail, sensitivity, and readout speed for deep-sky, planetary, lunar, and solar imaging.

Monochrome Imaging for Greater Control

Without a Bayer color filter array, the sensor captures incoming light directly at each pixel. This makes the ATR183M well suited to monochrome deep-sky imaging and, with LRGB or narrowband filters, detailed color composite photography with full control over individual wavelength channels.

Peak QE >80% for High-Sensitivity Imaging

The Sony IMX183 sensor delivers peak quantum efficiency above 80%, helping capture incoming light efficiently across a range of astronomical targets. Combined with ultra-low readout noise of 1.4–2.6 e⁻, this makes the ATR183M well suited to faint deep-sky objects, narrowband imaging, and high-resolution planetary work.

Is ATR183M Right for Your Astronomy Imaging Setup?

Deep-Sky Imagers Seeking Fine Detail

If your primary interest is deep-sky imaging, the ATR183M's 20MP resolution and 2.4 μm pixels resolve fine structure in galaxies, nebulae, and star clusters. Two-stage TEC cooling and ultra-low readout noise support long exposures with minimal thermal noise, while the 512MB DDR3 buffer maintains stable data transmission during extended imaging sessions.

Planetary, Lunar, and Solar Imaging Enthusiasts

The ATR183M also supports high-speed capture for planetary, lunar, and solar imaging. Hardware ROI and 8-bit mode increase frame rate by reducing the readout area, making it easier to collect large frame sequences for stacking and processing. Always use appropriate solar safety equipment for solar observations.

Astrophotographers Who Want One Camera for Multiple Targets

With its combination of high resolution, low readout noise, cooled long-exposure capability, and high frame rate modes, the ATR183M covers deep-sky and planetary imaging in a single camera. This makes it a versatile choice for astrophotographers exploring a wide range of targets.

Why Choose the ATR183M

ATR series DDR3 memory buffer

512MB DDR3 High-Speed Buffer

The built-in 512MB (4Gb) DDR3 buffer maintains stable data transmission, reduces USB transfer bottlenecks, and helps minimize amp-glow by buffering image data before it reaches the receiver—supporting a stable workflow for both long-exposure and high-speed imaging.

ATR series anti-condensation heating system

Anti-Condensation Heating

The ATR series optical window features an integrated smart heating system that actively measures ambient temperature and humidity. It automatically applies precise heat to prevent condensation, keeping your optical path crystal clear without introducing disruptive thermal air currents.

ATR series two-stage TEC cooling system

Two-Stage TEC Cooling

Equipped with an integrated heat dissipation structure and a high-efficiency dual-stage Thermoelectric Cooling (TEC) module with a controllable fan. It lowers the sensor temperature to 45°C below ambient, consistently maintaining a stable -5°C to -10°C even in peak summer. This allows for clean, long-exposure tracking up to 1 hour without thermal noise accumulation.

ATR183M Performance Analysis

The Sony IMX183 back-illuminated sensor offers strong sensitivity across the visible spectrum, with peak quantum efficiency above 80%. Its broad response supports deep-sky, planetary, lunar, and solar imaging, with added flexibility for capturing specific wavelengths using appropriate filters.

Frequently Asked Questions

Can I power my guide camera through the camera's built-in USB Hub?

Yes. The ATR series cameras connect with accessories through USB data connection and stable external power, allowing users to build a complete deep-sky imaging workflow with a telescope, mount, guide camera, computer or controller, and power supply.

Does the camera include a 12V power adapter, and is it mandatory for imaging?

Yes. All ToupTek Astro DSO cooled cameras require a regulated 12V 3A DC power supply for imaging. Please use the included factory power adapter or a high-quality lithium-ion battery with a stable 11V–14V output.

Will this camera work with my existing control software?

Yes. The ATR series features robust, industry-standard ASCOM and INDI drivers. It integrates seamlessly with all major open-source and commercial astronomy suites.

How do I achieve the standard 55mm backfocus with my telescope?

Achieving the industry-standard 55mm backfocus is precise and seamless. The optical train is configured via a modular three-stage connection sequence: a 17.5mm front adapter or tilter, a 20mm filter drawer or extension tube, and a 17.5mm Off-Axis Guider (OAG). This combination yields a perfect 55mm stack distance that connects natively to M48, M54, and M68 telescope interfaces, with simple adapter options available for M42 threads and 2-inch ports.

How does the Anti-Dew Technology work?

The ATR series utilizes a multi-layer defense system. The sensor chamber is industrially sealed with dry air to prevent internal frost. Simultaneously, a built-in electronic heating strip warms the protective window to prevent external dew under humid summer nights.
