IMX366 Sensor: High-Resolution Full-Frame Imaging with Exceptional Details
- 44.7MP Full-Frame Sensor for Exceptional Image Detail: 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.
- Optimized 4.40μm Pixels for Balanced Sensitivity and Resolution: 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.
- High Dynamic Range for Richer Image Details: 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.
Is SkyEye Plus Full-Frame & APS-C Camera for Astrophotography Worth it?
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:
Advanced Deep-sky Astrophotographers
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.
Imagers with High-End Optics & Complete Systems
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.
Why Choose the SkyEye45AC Plus
5 USB Ports for Simpler Imaging Setups
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.
Enlarged Front Window for Improved Illumination
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.
512MB DDR3 High-Speed Buffer
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.
High-Efficiency Amp-Glow Suppression
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.
Anti-Condensation Heating
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.
Two-Stage TEC Cooling
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.
SkyEye Plus Series Camera Specifications
ATR vs. SkyEye Plus: Which Series Do You Need?
The ATR Series offers a versatile and accessible solution for astrophotographers who prioritize flexibility, portability, and value, with sensor formats ranging from 1/1.2" to APS-C.

OSC vs. Mono: Which is Best for Your Setup?
One-Shot Color (OSC)
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)
Monochrome (Mono) cameras 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.
SkyEye45AC Plus Performance Analysis
The Sony IMX410C full-frame sensor combines a peak quantum efficiency exceeding 80% with excellent sensitivity for deep-sky astrophotography.
