It pairs the 2.5 mm CS-mount lens — which gives a 170° field on a 1\/2″ sensor — with an adjustable mini tripod to aim and steady the camera. Player One matches it to their 1\/2″-format cameras, the Neptune series in particular. The camera itself is not included.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you own (or are adding) a Player One Neptune-M, Neptune-C, or Neptune-C II and want a self-contained way to watch the whole sky — clouds moving in, meteors, satellites, or aurora — without building a mount from scratch.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2.5 mm CS-mount lens:\u003c\/strong\u003e a 170° field on a 1\/2″ sensor — an all-sky view.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable mini tripod:\u003c\/strong\u003e included, for aiming and steadying the camera at the sky.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatched to the Neptune series:\u003c\/strong\u003e the 170° coverage is stated for 1\/2″ cameras such as the Neptune-M, Neptune-C, and Neptune-C II.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal construction:\u003c\/strong\u003e compact lens and tripod for a simple, durable setup.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eOptical Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThe all-sky field is a product of focal length and sensor size: 2.5 mm projected onto a 1\/2″ sensor spans roughly 170°. The CS mount is the standard machine-vision lens interface used by compact astronomy cameras, so the lens seats at the correct back-focus on a CS-mount body without an adapter. The mini tripod holds the camera pointed at the zenith so the circular all-sky image sits centered in the frame.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eAll-sky monitoring — cloud cover, meteors, satellite passes, aurora — with a 1\/2″ Player One planetary camera, on a desk, windowsill, or fixed outdoor spot.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThe lens uses a CS mount and is matched to 1\/2″-format sensors such as the Neptune series.
