Explore the Solar System with the ToupTek ATR432M. Featuring Sony’s back-illuminated IMX432 monochrome sensor, 1.6MP resolution, and large 9µm pixels, this high-speed astronomy camera combines global shutter technology with rapid readout. Its fast acquisition makes it a practical choice for capturing the Sun, Moon, and planets, while its monochrome design provides flexibility across different optical filters. With a built-in 512MB DDR3 buffer and two-stage TEC cooling, the ATR432M supports stable data transmission and temperature-controlled imaging for a wide range of astrophotography workflows.
The Sony IMX432 sensor features a 1.1-inch optical format and large 9.0 μm pixels. Its pixel design supports strong light collection, making it suitable for capturing fine details in solar, lunar, and planetary astrophotography.
Without a Bayer color filter array, the monochrome sensor captures incoming light directly at each pixel. This provides flexibility for wavelength-specific imaging with suitable filters and makes the ATR432M well suited to specialized monochrome astrophotography workflows.
The global shutter captures the entire frame simultaneously, helping reduce rolling-shutter distortion during fast image acquisition. Combined with high-speed readout, it supports capturing transient details during brief periods of favorable atmospheric seeing.
The ATR432M's large pixels and high-speed readout make it a suitable option for solar imaging. Its global shutter supports consistent frame capture, while ROI settings can help increase frame rates when focusing on specific solar features.
For lunar and planetary imaging, high-speed capture helps record more frames during moments of good atmospheric seeing. The monochrome sensor also provides flexibility for working with appropriate filters and specialized imaging techniques.
The ATR432M supports monochrome imaging workflows that benefit from large pixels, adjustable gain, and flexible exposure control. Its cooled design also provides temperature regulation for imaging applications that require it.
The built-in 512MB DDR3 buffer temporarily stores image data before transmission, helping maintain stable data transfer during high-speed capture. It can also help reduce amp-glow associated with data transmission, though it does not eliminate amp-glow entirely.
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.
The two-stage thermoelectric cooling system features a controllable fan and PID temperature regulation. This helps manage sensor temperature during imaging sessions and supports more consistent operating conditions.
The global shutter captures the entire frame at once, helping reduce rolling-shutter distortion. This is especially useful for planetary and lunar imaging, where high-speed capture helps you collect more frames during moments of steady seeing.
The back-illuminated Sony IMX432 monochrome sensor offers a peak quantum efficiency of over 79%. Its monochrome design supports wavelength-specific imaging with suitable filters, providing flexibility for solar and other specialized astrophotography applications.
Which Series Do You Need
The ATR series features versatile sensors ranging from 1/1.2” up to APS-C (e.g., ATR585, ATR2600) to offer a balanced mix of performance and flexibility, whereas the flagship SkyEye Plus series incorporates APC-S (e.g., SkyEye26AM/AC Plus) and full-frame sensors (e.g., SkyEye62AM/AC Plus) to maximize light-gathering area and deliver expansive, uncropped fields of view.
Choose the acquisition workflow that matches your imaging goals
One-shot Color (OSC) cameras streamline your workflow by capturing full-color images without a filter wheel, offering a fast and travel-friendly setup that is perfect for astrophotography beginners, mobile imagers, or anyone seeking high-quality results with minimal post-processing.
Monochrome (Mono) cameras, however, deliver superior photon efficiency and pixel-level sharpness by eliminating the light loss and resolution interpolation of a Bayer matrix. Mono imaging is tailored for dedicated deep-sky astrophotographers who demand maximum sensitivity, ultimate narrowband performance (Hα, OIII, SII), and full control over composite LRGB rendering under any sky condition.
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.
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.
Yes. The ATR series features robust, industry-standard ASCOM and INDI drivers. It integrates seamlessly with all major open-source and commercial astronomy suites.
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.
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.
