Designed around the Sony IMX432 color CMOS sensor, the ATR432C combines large 9.0 μm pixels with global shutter technology and high-speed image acquisition. Its 1600 × 1100 resolution and fast readout make it suitable for capturing the Sun, Moon, and planets, while its color sensor records RGB information in a single exposure. A built-in 512MB DDR3 buffer helps maintain stable data transmission during capture, while two-stage TEC cooling with PID temperature regulation helps maintain controlled sensor temperatures. Together, these features provide a practical imaging solution for astrophotographers seeking high-speed color capture with temperature control.
The Sony IMX432 sensor features a 1.1-inch optical format and large 9.0 μm pixels. The pixel design supports light collection, making the ATR432C suitable for capturing solar, lunar, and planetary details. With 1600 × 1100 resolution, it offers a balance between image area and high-speed acquisition.
The color CMOS sensor records color information in a single exposure, eliminating the need to capture separate monochrome channels through RGB filters. This simplifies the acquisition process and provides a convenient workflow for solar, lunar, and planetary astrophotography.
The global shutter captures the entire frame simultaneously, helping reduce rolling-shutter distortion during fast image acquisition. Combined with readout speeds of up to 120 FPS at 8-bit over USB 3.0, it supports capturing fleeting details during brief periods of favorable atmospheric seeing.
The ATR432C combines high-speed readout with a color sensor, making it a practical option for solar imaging workflows that benefit from rapid frame acquisition. Its global shutter supports simultaneous frame capture, while hardware ROI allows users to focus on selected solar features and increase frame rates when a smaller readout area is sufficient.
For lunar and planetary imaging, atmospheric turbulence can cause image details to fluctuate from moment to moment. The ATR432C's high frame rate helps record more frames during favorable seeing conditions, while its color sensor captures RGB information in a single exposure.
The ATR432C combines color capture with two-stage TEC cooling and PID temperature regulation. This provides temperature control for imaging sessions that require it, while the color sensor keeps acquisition straightforward without separate RGB filter sequences.
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, but 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. The camera's temperature can be set to a target value, helping maintain controlled operating conditions during imaging sessions.
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 Sony IMX432 color sensor is designed for visible-light imaging, with a specified spectral response range of 380–690 nm when using the integrated IR-cut filter. Its color sensor captures RGB information in a single exposure, making it suitable for color astrophotography without the need for separate RGB filter sequences.
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.
