Ultra-High Resolution Full-Frame Imaging with Exceptional Detail
Powered by the Sony IMX366 full-frame CMOS sensor, SkyEye45AC Plus delivers an impressive 44.7MP resolution (8192 × 5460 pixels), combining outstanding image detail with excellent sensitivity for advanced deep-sky astrophotography. Featuring 4.40μm pixels, 14-bit ADC, up to 40°C below ambient cooling, optimized amp-glow suppression, and a 512MB DDR3 buffer, SkyEye45AC Plus provides stable and reliable performance for long-exposure imaging. Designed for astrophotographers seeking maximum detail, it is ideal for capturing wide-field nebulae, galaxies, and rich star fields with exceptional clarity.
The Sony IMX366 full-frame sensor delivers 8192 × 5460 resolution, enabling astrophotographers to capture intricate details of galaxies, nebulae, and large-scale celestial objects. Its expansive imaging area helps fully utilize the telescope’s imaging circle and provides a wider field of view for deep-sky photography.
The 4.40μm pixel size provides an excellent balance between photon collection efficiency and image resolution, allowing SkyEye45AC Plus to reveal faint nebular structures and fine astronomical details with excellent clarity. Combined with a peak quantum efficiency exceeding 80%, the sensor delivers strong signal performance for challenging deep-sky targets.
With up to 73ke⁻ full well capacity and read noise as low as 0.88e⁻ in HCG mode, SkyEye45AC Plus preserves both bright star cores and faint background structures. The result is cleaner images, smoother gradients, and greater flexibility during post-processing.
Designed to cover a wide range of astrophotography needs, the SkyEye Plus Series offers both Full-Frame and APS-C cameras, giving imagers the flexibility to choose the sensor format that best matches their telescope, imaging targets, and workflow. From wide-field deep-sky imaging to high-resolution capture of faint celestial structures, SkyEye Plus combines advanced sensors, deep cooling, low read noise, and high dynamic range for consistently clean, detailed results. SkyEye Plus is specially engineered for:
Designed for experienced imagers, deep-sky enthusiasts, and remote observatory users who demand high sensitivity, low noise, excellent dynamic range, and reliable performance for demanding imaging projects.
Whether you're using a compact telescope with an APS-C image circle or a premium optical system designed for full-frame coverage, SkyEye Plus offers the sensor format to match your setup. Full-frame models maximize field of view and optical coverage, while APS-C models provide an excellent balance of resolution, sensitivity, and system compatibility.
Featuring an onboard 512MB DDR3 buffer, the SkyEye Plus series camera ensures stable USB 3.0 data transfer, preventing frame loss and transmission-induced amp-glow. The camera supports digital pixel binning from 1x1 to 8x8 (via stacking or averaging) and hardware pixel binning from 1x1 to 3x3 (via averaging). On-sensor hardware binning provides significantly faster readout speeds and processing efficiency than software binning.
The integrated 5-port USB hub (4*USB2.0, 1*USB3.0) allows direct connection of accessories such as filter wheels, guide cameras, and focusers, reducing cable clutter and simplifying setup.
The enlarged front window of the SkyEye Plus full-frame camera improves illumination across the sensor and enhances compatibility with fast optical systems and larger imaging circles.
SkyEye45AC Plus is equipped with advanced amp-glow suppression technology, delivering a cleaner background and enhanced signal integrity for long-exposure deep-sky imaging. This helps astrophotographers capture faint celestial details with greater confidence and efficiency.
Note: A minimal level of residual glow may remain under certain conditions. However, it can be effectively removed through standard dark-frame calibration without affecting the final image quality.
The SkyEye Plus 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 camera utilizes a high-performance two-stage Thermoelectric Cooling (TEC) system. By achieving a cooling from -35°C to -42°C below ambient*, the SkyEye Plus series camera cools the sensor deeply and consistently, delivering exceptionally quiet background noise levels for long-exposure imaging.
*Note: Cooling performance may vary by model. Please refer to the product manual for detailed specifications.
The Sony IMX366 full-frame sensor delivers a balanced combination of sensitivity, resolution, and dynamic range, with quantum efficiency exceeding 80% for efficient photon capture. In HCG mode, SkyEye45AC Plus achieves read noise as low as 0.88e⁻, while LCG mode provides up to 73ke⁻ full well capacity, enabling astrophotographers to capture faint deep-sky structures while preserving details in brighter regions.
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 series incorporates full-frame (35mm) and large-format sensors (e.g., SkyEye62AM) 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 (Ha, OIII, SII), and full control over composite LRGB rendering under any sky condition.
The SkyEye62AM requires a regulated 12V 3A DC power supply for stable imaging and cooling performance.
Yes. The SkyEye62AM uses the Sony IMX455M full-frame monochrome CMOS sensor.
The monochrome sensor records incoming light without a Bayer color filter array, supporting high photon efficiency and detailed LRGB or narrowband imaging.
Use a telescope and corrector that can provide a flat image circle of approximately 44mm or larger so the full-frame sensor is properly illuminated.
For the imaging train, wide-clear-aperture M48 or M54 connections and large-format filters such as 2-inch or 50mm filters are recommended. Undersized adapters, filter wheels, or filters can restrict the light path and introduce vignetting near the frame edges.
The SkyEye62AM uses a two-stage Thermoelectric Cooling (TEC) system and can maintain a temperature differential of up to approximately 35°C below ambient temperature.
Actual cooling performance depends on ambient temperature, ventilation around the camera, the stability of the 12V 3A power supply, and the load from the optical-window heater. Keep the fan and airflow unobstructed for stable long-exposure operation.
The SkyEye62AM provides two backfocus configurations:
Use the selected configuration when calculating the total spacing for your corrector, filter wheel, off-axis guider, and other imaging-train components.
