Meet SkyEye26AM Plus
Advanced IMX571 APS-C Cooled Cameras for Deep-Sky Imaging
Powered by the Sony IMX571 APS-C sensor, the SkyEye26AM Plus (Mono) and SkyEye26AC Plus (Color) deliver 26MP resolution, 3.76μm pixels, and a 16-bit ADC for detailed, high-quality deep-sky imaging. Featuring advanced two-stage TEC cooling with up to 43°C temperature reduction, ultra-low read noise, zero amp-glow performance, and a 512MB DDR3 buffer, they provide clean, stable images during long exposures.
IMX571 Sensor: The Ideal Balance of Resolution, Sensitivity, and Dynamic Range
Back-Illuminated for Higher Sensitivity
The advanced BSI architecture provides excellent quantum efficiency, reaching >80% for the color version and >91% for the monochrome version, enabling efficient photon collection for faint deep-sky objects.
Ultra-Low Noise, Wide Dynamic Range
With up to 51ke⁻ full well capacity and read noise as low as 0.77e⁻ (Mono) and 0.79e⁻ (Color), the IMX571 delivers excellent dynamic range for capturing both faint structures and bright stellar details.
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 SkyEye26AM Plus
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.
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.
Zero Amp-Glow Technology
The SkyEye Plus series (except SkyEye45AC) camera features a specialized zero amp-glow circuit design that maintains a clean, perfectly uniform sensor background across multi-minute long exposures, protecting the faintest details of delicate nebulae.
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.
SkyEye26AM Plus Performance Analysis
Powered by the Sony IMX571 APS-C sensor, SkyEye26AM/AC Plus combines excellent sensitivity, low noise, and wide dynamic range for advanced astrophotography. The color version delivers quantum efficiency exceeding 80%, while the monochrome version achieves over 91% QE for enhanced photon capture in LRGB and narrowband imaging. With HCG mode reaching read noise as low as 0.79e⁻ (Color) and 0.77e⁻ (Mono), and LCG mode providing up to 51ke⁻ full well capacity, the IMX571 enables cleaner images, smoother gradients, and reliable performance across a wide range of deep-sky targets.
ATR vs SkyEye
Which Series Do You Need
Sensor Format
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.
OSC or Mono
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.
What's in the Box
Frequently Asked Questions
What power supply does the SkyEye62AM require?
The SkyEye62AM requires a regulated 12V 3A DC power supply for stable imaging and cooling performance.
- Use the supplied factory power adapter whenever possible.
- For field use, choose a high-quality lithium-ion battery with a stable 11–14V output.
- Avoid unstable or falsely rated power supplies, which may interrupt cooling or image capture.
What sensor does the SkyEye62AM use, and is it a full-frame camera?
Yes. The SkyEye62AM uses the Sony IMX455M full-frame monochrome CMOS sensor.
- Sensor format: 36 × 24mm full frame
- Resolution: 61MP (9576 × 6388)
- Pixel size: 3.76μm
The monochrome sensor records incoming light without a Bayer color filter array, supporting high photon efficiency and detailed LRGB or narrowband imaging.
What optical setup is recommended for the SkyEye62AM full-frame sensor?
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.
What is the cooling performance of the SkyEye62AM?
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.
What is the backfocus of the SkyEye62AM?
The SkyEye62AM provides two backfocus configurations:
- 17.5mm with the detachable 5mm front adapter installed.
- 12.5mm with the 5mm front adapter removed.
Use the selected configuration when calculating the total spacing for your corrector, filter wheel, off-axis guider, and other imaging-train components.
