{"product_id":"neptune-664c-usb3-0-color-camera","title":"NEPTUNE 664C USB3.0 Color Camera","description":"\u003cp\u003eThe Player One Neptune 664C is a USB3.0 colour camera built around the 1\/1.8\" Sony IMX664 back-illuminated CMOS sensor. It combines a generous 4.2-megapixel field with a deep full-well and fast frame rates, making it a well-balanced planetary and lunar imager that also handles bright wide-field solar-system scenes.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eProduct Overview\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe IMX664 provides a 2704×1540 array of 2.9µm pixels across a 9 mm diagonal. A 38.5k e⁻ full-well gives wide dynamic range, read noise falls to about 0.67 e⁻, the ADC is 12-bit, and peak QE reaches roughly 91%. Over USB3.0 it captures up to 93 FPS in Raw8 and 46.5 FPS in Raw16 at full resolution, so you can bank long capture runs during steady seeing.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis is a good match if you image the Moon and planets and want a larger, high-sensitivity colour sensor with strong dynamic range. Its field also frames more of the lunar disc than a 1\/2.8\" chip, and it autoguides through its ST4 port.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSony IMX664 colour sensor:\u003c\/strong\u003e 1\/1.8\" back-illuminated CMOS, 4.2 MP, with high peak QE near 91%.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeep 38.5k e⁻ full-well:\u003c\/strong\u003e wide dynamic range for bright planetary and lunar highlights.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast capture:\u003c\/strong\u003e up to 93 FPS in Raw8 at full 2704×1540 resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow read noise:\u003c\/strong\u003e down to about 0.67 e⁻ at higher gain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e256MB DDR3 buffer:\u003c\/strong\u003e stabilizes high-speed transfer to avoid dropped frames.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eST4 autoguide port:\u003c\/strong\u003e doubles as a guide camera.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtective window:\u003c\/strong\u003e D21×1.1 mm with AR Plus multi-layer anti-reflection coating.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eOptical \/ Mechanical Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Neptune 664C uses a rolling-shutter colour CMOS with an RGGB Bayer matrix and 2.9µm pixels. Its deep full-well and 12-bit ADC suit bright, high-cadence solar-system targets. The sensor sits at a 12.5 mm back focal distance, and the 66 mm body threads accept 1.25\" and M42×0.75 (T-thread) adapters. Exposures run 32µs to 2000 s.
