Player One Neptune 664C Color Camera (Neptune-664C)

Player One Neptune 664C Color Camera

NEPTUNE 664C opened NEPTUNE 3rd Gen gate,  the newest planetary camera which developed by Player One Astronomy. A successor of Neptune-C II (IMX464) camera. NEPTUNE 664C camera adopts the Sony IMX664 1/1.8” color sensor. 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.

Super AR Plus window

NEPTUNE 664C using this Super AR Plus window in front of it. This window glass can give super high transmittance from 310nm to 1100nm. This important improvement, make NEPTUNE 664C camera has much better performance in both Ultravoilet and NIR.

The naming of Player One Astronomy cameras is unique. For example, we name the planetary cameras after planets (They are Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune, Earth is not included). The size of each planet to a certain extent represents the size of camera sensors. We will name Saturn with a 1-inch sensor camera, and for Mars, we will name it with a ½.8 inch sensor camera. All names will be engraved on the housing of the cameras.

STARVIS 2 Technology

NEPTUNE 664C based on Sony newest STARVIS 2 technology, it is back-illuminated pixel technology used in CMOS image sensors.

on-Amp-Glow

Biggest supprise of NEPTUNE 664C camera is, its dark frame is totally “dark”, whatever we strength the curve, there is no AMP glow at all!

Cutting-edge Design

The planetary cameras developed by Player One Astronomy use a scientific and technological regular hexagon to construct the main body line, supplemented by round chamfers to achieve both rigidity and flexibility. 

2nd Gen – Sensor Tilt Plate

The built-in high-density sponge shading pad can block the light from the side slits without any side leakage.

When taking solar photograph with prominence telescope, the Newton ring is annoying. Smoother solar image without Newton ring could be taken by adjusting the focal plate. Get a much smaller field curvature of the telescope.

256M DDR3 Cache

Player One Astronomy cameras are the first ones who adopt the DDR3 cache in all planetary cameras in the world! It helps stabilize and secure data transmission, effectively avoids frame dropping, and greatly reduces read noise.

With the DDR3 cache, the camera does not have high demands on computing needs any longer, it will still have excellent performance even if it is connected to a USB 2.0 port.

DPS technology

The planetary cameras from Player One Astronomy have DPS (Dead Pixel Suppression) technology. The DPS is anaylse many dark frames to find out thoes fixed abnormal pixel and record the map in camera memory. In imaging, each exposure frames, thoes position of dead pixels will be given a median value according to the active pixels around that abnormal pixel.

Passive Cooling System

Player One add a new feature called Passive Cooling System to conduct the heat from the sensor out.

Overvoltage and overcurrent protection mechanism

Player One cameras produced by the number one player ensure the safety of your camera and other equipment through overvoltage and overcurrent protection mechanisms.

Data Port

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 you use a high-quality solid-state drive to record data to give full play to the performance of the camera.

Use the ST4 guide cable to connect the camera and the AUTO GUIDE port of the equatorial mount to do the guiding.

Performance

HCG open at gain=180.

Readout Noise

Regarding readout noise, we solemnly promise that all values are obtained from actual tests.  And for users, you could use Sharpcap 4 for testing. SC4 has a function called Sensor Analysis, provide a very simple way to test readout noise.

After many rigorous readout noise tests, the camera can reach a low readout noise of 0.75e at a gain of 350 and around 0.67e at a gain of 450.

If you are interested in readout noise testing, you may try it yourself, which is very simple.

HCG  Mode

NEPTUNE 664C camera has a unique 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.

QE Curve

The QE curve of the NEPTUNE 664C camera tell us that this camera is NIR enhanced camera. working after Super AR Plus window, this camera will keep very high QE in infrared.

This is the relative QE curve which provided by Sony, the absolute QE peak about 91%.
