SKU: Neptune-C II Category:


The Neptune series is a 1/2-inch format planetary camera series for the top player. It is larger than 1/3-inch and has a higher resolution, and is more suitable for astronomy enthusiasts.

The main hit of the Neptune series is Neptune-C II, yes, you read it right. We directly released the second-generation Neptune model on the grounds that the plan could not keep up with the changes.

Neptune-C II camera uses Sony’s latest IMX464 chip, which is bigger than IMX462. Neptune-C II is also the world’s first planetary camera with IMX464 chip.

Product Description

Neptune-C II is a planetary camera developed by Player One Astronomy, which adopts the Sony IMX464 1/1.8” format sensor. The 2.9um pixel size accommodates a well depth of 12ke with a total of 4.2MP  (the resolution is 2712*1538), and the diagonal is 9mm.

Everyone should know that the rookie IMX462 chip currently on the market has become the new favorite of planetary shooting, and IMX464, as a product of the same process, is equivalent to an enhanced version of IMX462, with a larger target surface and higher resolution. Come for a better shooting experience.


0.7e ultra-low read noise

Compared with the IMX178 of the same frame, the read noise of Neptune-C II can be as low as 0.7e, and the noise is reduced by about 47%, which is as strong as IMX462!

Sensitivity increase

Compared with another 1/1.8 inch chip IMX178, we find that the IMX464 pixel is larger than the IMX178 at 2.4um, reaching 2.9um.

When used on the same telescope, although the quantum efficiency is not much different, the 2.9um pixel has 46% larger photosensitive area than the 2.4um pixel, which can greatly increase the single pixel to obtain more photons, which means Sensitivity has also been greatly improved.

Near infrared super light sensitivity

Not only that, IMX464 also has ultra-sensitive infrared sensitivity characteristics, suitable for playing infrared photography, whether it is matched with IR685, IR850 or CH4 filters, it will give you a new visual experience.

Ultra high frame rate

Neptune-C II can reach 93FPS at full resolution, which is 55% higher than the 60FPS of the IMX178 chip of the same size, making it more efficient to shoot planets.


The fun thing is, with the strong ability in capturing infrared lights and the super high sensitivity, the Neptune-C II camera can be used as a monochrome camera with an IR850 filter or CH4 filter to capture infrared lights.

Connecting the Neptune-C II camera to a telescope with an 1.25″ T-Mount, or adding a Barlow lens between the camera and a telescope to extend the focal length for more details.

With a CS lens attached on the Neptune-C II camera,it can be used as an all-day camera or meteor monitoring camera.


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 Neptune, we will named it with  a 1/1.8 inch senor camera. All names will be engraved on the housing of the cameras.

Cutting-edge Design

The planetary cameras developed by Player One Astronomy uses a scientific and technological regular hexagon to construct the main body line, supplemented by round chamfers to achieve both rigidity and flexibility. The positive red, which is like a summer fire, is matched with the low-key and steady black, and the super-fine frosting process on the entire surface makes the camera look luxurious and cool, highlighting the style of high-end players, can’t take my eyes off 😀

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 one who adpots the DDR3 cache in all planetary cameras in the world! It helps stabilize and secure data transmission, it effectively avoids frame dropping and greatly reduces readnoise.

With the DDR3 cache, the Mars-C camera does not have high demands on computing needs any longer, it will still has 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.

Overvoltage and overcurrent protection mechanism

Player One cameras produced by the number one player ensures 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 full-resolution preview is used, it can reach 93 FPS in RAW8 mode (10bit ADC). 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 guiding.





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.

We wrote a tutorial on our website:

After many rigorous readout noise tests, the Neptune-C II camera can reach a low readout noise of 0.75e at a gain of 350 and around 0.71e at a gain of 400.

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

HCG  Mode

The Neptune-C II camera has a unique HCG mode, which will automatically turn on when the camera gain setting is ≥83. The HCG mode can greatly reduce the readout noise and retain the same high dynamic range as the low gain.

  1. Luis

    Is this camera compatible with ASIAIR?

    • MoonPrince

      If they can public the interface of asiair, we can do it.

  2. Swan.R

    This is my first camera from P1. It’s for planetary imaging very well. I did some imaging this summer, both lunar and planetary, I got some impressvie result. This camera is really awesome, stable and fast.

  3. Happy Range

    This is the one I want to buy next. I was interested in IMX462 cameras. when I saw this one, I know it’s my next target. bigger sensor, and interesting NIR performance. Just perfect!!

  4. midnight.telescope

    Very impressed by speed and sensitivity! Supports any size custom area of interest. Has full support in both FireCapture and SharpCap. Didn’t have any issues yet, however there is one dead green pixel near to center of field of view so I have to use hot pixel filter in FireCapture to trim it.

    • MoonPrince

      Hi there,
      If convinient, please send us a email to :
      We can remote do DPS again and rewrite the new map of dead pixels of your camera.

  5. Edmondo678

    It’s my first P1 camera in my life. I’m very pleased with the performance of this camera. Almost used it for a year. Sorry for my late review 🙂

    • Player One Astronomy

      Thank you, Edmondo. It’s not late, we are happy to know 🙂

  6. Maximilian Thomas (verified owner)

    Very pleased with the camera and the company!

  7. rpopovich (verified owner)

    Have been very pleased with the camera doing lunar, planetary images. Also using an IR742 pass filter this works extremely well as a guide camera using PHD2.
