ZEUS 455C Pro

Player One ZEUS 455M PRO

Key Features

• Sony IMX455 Full-Frame CMOS Sensor:
  61 megapixels (9576 x 6388), 3.76 µm pixel size, ~44.3 mm diagonal color sensor.
• Deep Cooling System:
  Dual-stage TEC cooling achieves ΔT of up to ~35 °C below ambient, minimizing thermal noise.
• Rear 4-Point Sensor Tilt Plate:
  Precise tilt adjustment at four corners reduces field curvature. Includes high-density sponge shading pad to prevent side-light leakage.
• 512 MB DDR3 Buffer:
  Stabilizes data transmission, prevents frame drops, and lowers readout noise-even on USB 2.0 ports.
• STARVIS Back-Illuminated CMOS:
  High quantum efficiency (~91%), excellent sensitivity for narrowband capture.
• Native 16-Bit ADC:
  Enables 65,536 tonal levels for smooth grayscale gradients and precision imaging.
• Dual Sampling Modes:
  Normal mode delivers higher frame rates, while Low-Noise (HCG) mode reduces read noise (~4.2 e⁻ → ~1.5 e⁻) and boosts dynamic range.
• Non-Amp-Glow Design:
  Minimal glow artifacts on long exposures, producing cleaner scientific frames.
• Robust Mechanical Design:
  Full-frame octagonal body made from frosted anodized surfaces, optimized for strength and thermal performance.

Why Choose This Product?

• Massive Full-Well Capacity:
  Boasts ~71.6 ke⁻ full-well - nearly identical to QHYs flagship full-frame sensors and ideal for high-dynamic-range capture.
• Superior Quantum Efficiency:
  Color sensor delivers ~80% QE at peak - excellent for dual narrowband imaging.
• Dual Sampling Modes Offer Flexibility:
  Normal mode for planetary speed; HCG mode for deep-sky imaging with low noise and retained dynamic range (~14.2 stops).
• Full Frame, Huge Resolution:
  61 MP at 44.3 mm diagonal delivers expansive field and pixel-level detail unmatched in APS-C sensors.
• Cooling and Anti-Dew Integration:
  TEC cooling with anti-fog control enables stable imaging in humid or temperature-variable environments.
• Buffered Data Stability:
  512 MB DDR3 buffer ensures consistent performance, even when capturing large RAW16 files via USB 2.0.
