Player One NEPTUNE-C II Color (SKU: POA-NEPTUNE-C-II ) is the second generation of the popular Neptune series planetary camera. Equipped with the latest Sony IMX464 COLOR (STARVIS 2) sensor in 1/1.8″ format with a resolution of 4.2 MP (2712 × 1538 px), it combines excellent quantum sensitivity (~85%), ultra-low readout noise < 1 e- (HCG mode) and zero amp-glow . USB-C 3.0 electronics and a 256 MB DDR-III buffer provide smooth recording up to 144 fps in full frame RAW10, making the camera an excellent tool for fast color astrophotography ( lucky imaging ) of the Moon, Sun and planets.
