SkyEye26AM Plus: Stronger Cooling & Wider Compatibility!
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.
Core Highlights of the SkyEye Plus
Shorter Back Focus
Every model uses an M54x0.75 female thread and includes a full-size M54 extension tube and adapter ring for a standard 55mm optical train. Removing the front adapters reduces the camera back focus to 12.5mm or 8.5mm for greater compatibility with optical systems and accessories.
Large Field of View
Featuring a Sony IMX571 back-illuminated mono sensor with 26 million effective pixels, this APS-C format delivers an excellent balance of performance and field of view. Its versatile sensor size pairs well with a wide range of telescopes and imaging setups, making it a strong choice for both experienced astrophotographers and beginners.
Powerful 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.
Expanded Connectivity & Reinforced Power
The integrated 5-port USB hub (4xUSB 2.0, 1xUSB 3.0) allows direct connection of accessories such as filter wheels, guide cameras, and focusers, reducing cable clutter and simplifying setup.
The optimized power system maintains stable camera operation during continuous cooling and high accessory loads throughout an imaging session.
- Note: The SkyEye Plus camera body can operate from a 12V/3A supply. A DC 12V/5A supply is strongly recommended when using the USB hub. USB 3.0 is used only for high-speed data transfer and does not power the camera or connected accessories.
Built-in Sensor Tilt Adjustment & Convenient Calibration
The SkyEye Plus body includes three sets of precision adjustment screws, allowing the sensor plane to be aligned with the telescope focal plane without an additional accessory for more uniform stars across the field.
- Note: Avoid large adjustments. Loosen the opposing screw before turning any adjustment screw. For example, loosen the matching push screw counterclockwise before tightening a pull screw clockwise; otherwise, the mechanism may be damaged.
- The series also supports the SkyEye rear four-point sensor tilt ring. The replacement does not consume additional optical length and retains the standard 12.5mm/17.5mm back focus.
High-Speed Buffer, Stable Transfer
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.
Zero Amp-Glow for Cleaner Long Exposures
SkyEye26AM Plus uses Sony's back-illuminated non-glow CMOS sensor, which effectively avoids the common glow problem of traditional front-illuminated sensors and maintains a uniform and clean background signal under high gain and long exposure conditions. Calibration is easier and post-processing is more efficient.
Anti-Dew 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.

Performance Analysis Charts
The SkyEye26AM Plus gives you greater control over image quality with three selectable gain modes, allowing you to optimize performance for everything from bright targets to faint deep-sky objects.
-
Native High-Bit-Depth ADC: SkyEye26AM Plus is equipped with 16bit ADC, with natural colors and delicate levels.
-
High sensitivity & high QE: The peak quantum efficiency of SkyEye26AM Plus is >91%, the spectral response is wider, the light sensitivity is more sensitive, and the ability to capture weak light signals is greatly improved.
-
HCG Mode: Reduces read noise for capturing faint targets, reaching as low as 0.77e⁻ read noise at maximum gain.
-
LCG Mode: Expands full-well capacity to help prevent overexposure and preserve detail in brighter targets.
-
Low Noise Mode: Reduces frame rate for lower read noise while maintaining high dynamic range and natural brightness and color.
