Player One Astronomy has announced the release of its latest planetary camera series, the Player One NEPTUNE 664C color camera which is the successor to the Neptune-C II, which adopted the Sony IMX464 1/1.8” format sensor.
The camera utilizes the latest Sony IMX664 1/1.8” color sensor which incorporates the Sony STARVIS 2 back-illuminated pixel technology. The 2.9um pixel size accommodates a well depth of 38.5ke with a total of 4.2MP (the resolution is 2704*1540), and the diagonal is 6.46 mm.
The Player One NEPTUNE 664C uses Super AR Plus window glass in front of the camera which gives high transmittance from 310nm to 1100nm. With this improvement the make NEPTUNE 664C has much better performance in both Ultraviolet and NIR.
The camera can be connected to a telescope with a 1.25″ T-Mount, or by a Barlow lens between the camera and a telescope to extend the focal length. With a CS adapter and fisheye lens attached to the camera, the camera can be utilized as an all-sky camera. You can use the ST4 guide cable to connect the camera and an autoguide port of the equatorial mount to do guiding.
The NEPTUNE 664C can reach a low readout noise of 0.75e at a gain of 350 and around 0.67e at a gain of 450. It offers an HCG mode, which will automatically turn on when the camera gain setting is ≥180. The HCG mode can greatly reduce the readout noise and retain the same high dynamic range as the low gain.
The camera utilizes DDR3 cache which helps stabilize and secure data transmission, which effectively helps avoids frame dropping and greatly reduces read noise. With the DDR3 cache, the camera does not require high computing demands and still offers excellent performance even when connected to a USB 2.0 port.
The Player One NEPTUNE 664C also offers DPS (Dead Pixel Suppression) technology, where dead pixels, including hot pixels and cold pixels of the image, are swept away.
When the camera is connected to the USB3.0 interface and a full-resolution preview is used, it can reach 93 FPS in RAW8 mode (10bit ADC), and the frame rate in RAW16 mode (12bit ADC) is 46.5 frames per second. When recording images, since the actual writing speed will be affected by the writing speed of the hard disk itself, when the hard disk writing speed is slow, the recording may not reach the theoretical speed. It is recommended that using a high-quality solid-state drive to record data to give full play to the performance of the camera.
