Poseidon-C Pro

Designed for vivid deep-sky capture, the Player One Poseidon-C Pro is a high-end cooled color camera built for astro imaging excellence.

Key Features

• Sony IMX571 APS-C CMOS Sensor:
  26 megapixels (6252 x 4176), 3.76 µm pixel size, ~28.3 mm diagonal sensor.
• Deep Cooling System:
  Dual-stage TEC cooling achieves delta-T of up to 40 °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 (~80%), excellent low-light sensitivity.
• Native 16-Bit ADC:
  Enables 65,536 discrete output levels for smoother tonal transitions and richer color detail.
• High Frame Rate Performance:
  Up to ~15 fps in RAW8 and ~7 fps in RAW16 at full resolution (6252×4176) over USB 3.0.
• Non-Amp-Glow Design:
  Minimal glow artifacts on long exposures, producing cleaner images and reducing the need for dark frames.
• Robust Mechanical Design:
  Octagonal body made from frosted black and red anodized surfaces, with round chamfered edges for both durability and style.

Why Choose This Product?

• Outstanding Full-Well Capacity: Offers ~71.7 ke⁻ full-well depth - more than 1.4x the standard IMX571 spec (~50 ke⁻), and nearly matching QHYs high-well variants.
• Dual Sampling Modes for Precision Control: In Low-Noise Mode, you get ≈3.96 e⁻ read noise with max dynamic range (~14.26 stops); switching to HCG Mode lowers read noise to ≈1.36 e⁻, ideal for narrowband imaging.
• Enhanced Dynamic Range Performance: Native 16-bit ADC delivers 65,536 tonal levels - preserving rich gradients and color fidelity through post-processing.
• Superior Thermal and Amp-Glow Suppression: STARVIS sensor and dual-stage TEC cooling (up to ~-40 °C) result in ultra-clean frames with negligible amp-glow, even at long exposures.
• Rear 4-Point Tilt Plate Included: Enables fine-grained tilt adjustment without dismounting the camera - a workflow advantage over many front-only tilt systems.
• Reliable Data Transmission Across USB Versions: Built-in 512 MB DDR3 buffer ensures smooth image streaming and reduced frame drop risk - even over USB 2.0.
