Technology Advantages
Full Frame 61-Megapixel Sensor
SkyEye62AM features the Sony IMX455 monochrome sensor with 61-megapixel ultra-high resolution (9568×6380) and a full-frame size of 35.976mm × 23.989mm. The 3.76μm pixel size ensures excellent light gathering capability while maintaining high resolution. The full-frame sensor guarantees an extremely large field of view, making it the ideal choice for capturing large nebulae, galaxies, and wide-field deep sky objects.
Sony IMX455 Spectral Response Curve
The SkyEye62AM sensor has a G sensitivity of 435.5mV at 1/30s. Its quantum efficiency peak exceeds 80% and maintains excellent response throughout the visible and near-infrared ranges. With an AR anti-reflection filter installed, its spectral response range is 380-1100nm. The sensor's high quantum efficiency ensures clear image capture even in low-light conditions, making it particularly suitable for photographing faint deep sky objects.
16-bit ADC and Flexible ROI
SkyEye62AM outputs native 16-bit ADC, providing 65,536 grayscale levels capable of capturing extremely fine brightness variations. This high bit depth is crucial for deep sky photography, enabling simultaneous recording of the bright core and faint outer details of nebulae. The camera supports hardware ROI, with smaller ROI sizes achieving higher frame rates.

512MB DDR3 Cache Technology
SkyEye62AM features 512MB (4Gb) DDR3 cache, helping maintain data transmission stability and effectively reducing amp-glow phenomena, as image data can be buffered without rushing to send data to the receiving end.
Pixel Binning Technology
SkyEye62AM supports digital pixel binning from 1×1 to 8×8 (stacking or averaging methods) and hardware pixel binning from 1×1 to 3×3 (averaging method). Hardware pixel binning is much more efficient than software pixel binning.
HCG/LCG Dual Mode Conversion Gain
SkyEye62AM supports HCG and LCG mode conversion. In LCG mode, its full well capacity can reach 111ke⁻.
Zero Amp-Glow Design
SkyEye62AM is carefully designed to achieve zero amp-glow photography. It's easy to see that images captured by SkyEye62AM exhibit no amp-glow phenomena.
Ultra-Low Noise Read Mode
SkyEye62AM's read noise is as low as 0.9 - 1.95 e⁻ (Low Noise Mode). This is impressive, as SkyEye62AM features a low noise mode, which means users can select low noise mode to achieve even lower read noise at the cost of reduced frame rate.
Precision Cooling System
Two-Stage TEC Deep Cooling Technology
SkyEye62AM's cooling system is a two-stage thermoelectric cooling (TEC) system with controllable electric fan-assisted heat dissipation. The TEC system is controlled by PID algorithm, allowing precise adjustment to target temperature with 0.1°C deviation. Operating temperature can be adjusted to specific values, with effective cooling difference reaching up to 35℃ below ambient temperature. This efficient cooling system ensures the stability of ultra-low noise mode and camera image quality.
TEC Cooling Structure
Adopts two-stage semiconductor cooling chip series design, where the first stage directly cools the sensor and the second stage efficiently conducts heat to the heat dissipation system.
Anti-Dew Heating System
The camera front end is equipped with an intelligent anti-dew heating system that automatically monitors environmental humidity and temperature, activating heating when necessary to prevent optical window condensation.

Multi-Mode Flexible Switching
SkyEye62AM supports HCG (High Conversion Gain) and LCG (Low Conversion Gain) mode conversion. In LCG mode, its full well capacity can reach 111ke⁻.
HCG Mode Performance
Camera Settings: Full Resolution, RAW 16-bit Mode, Temperature: -5℃
HCG (High Conversion Gain) mode is optimized for deep sky astrophotography. In this mode, read noise can be as low as 0.97e⁻, making it ideal for capturing faint nebulae, galaxies, and other deep sky objects. With a full well capacity of 51ke⁻ and dynamic range reaching 14.15 stops, it can simultaneously capture both the bright core and faint outer structures of celestial objects.
LCG Mode Performance
Camera Settings: Full Resolution, RAW 16-bit Mode, Temperature: -5℃
LCG (Low Conversion Gain) mode provides larger full well capacity (111ke⁻), suitable for capturing high dynamic range celestial objects. Dynamic range can reach 14.7 stops, ensuring complete recording of all details from brightest to darkest.
Low Noise Read Mode
Optimized for extreme low-light photography
Low noise read mode achieves ultra-low noise levels of 0.9-1.95e⁻. While the frame rate decreases to 1.9 FPS (16-bit), for deep sky photography requiring long exposures, the signal-to-noise ratio improvement from ultra-low read noise makes this sacrifice completely worthwhile.
Camera Interface & Dimensions
Flexible Back Focus Design
The upgraded SkyEye62AM with new housing has the capability to switch back focus lengths. By removing the 5mm back focus ring from the camera's front end, the camera's occupied back focus length changes from 17.5mm to 12.5mm, effectively adapting to non-standard back focus optical systems and more flexible equipment configurations.
Sensor Tilt Adjustment
SkyEye62AM has the capability to adjust sensor tilt. Three sets of screws can be used to adjust the image sensor tilt angle to make it parallel to the telescope's primary mirror surface, with each set containing one screw for pulling back and one for pushing forward.
