Player One Poseidon-M PRO Mono (SKU: POA-POSEIDON-M-PRO) is a premium, cooled camera for deep-sky astrophotography. At the heart of the device is the Sony IMX571 mono sensor in APS-C format (26 MP, 6252 × 4176 px). A 3.76 µm pixel, native 16-bit ADC, 71.7 ke- well and peak QE ≈ 91 % provide exceptionally high dynamic range and excellent sensitivity - even in the near infrared. A two-stage TEC module lowers the sensor temperature by ≈ 40 °C below ambient, while a 512 MB DDR-III buffer guarantees stable data transfer without dropped frames.

Key Features

• Sony IMX571 mono matrix (APS-C, 26 MP, 3.76 µm pixel, no amp-glow)
