Player One Mars-M II (IMX462) 2.1MP Mono Camera Astronomical Camera Planetary Camera for Planets


Product Description:
Mars-M II is a very anticipated monochrome camera. It is the newest planetary camera developed by Player One Astronomy. We wait for this monochrome sensor for 2 years. Mars-M II (IMX462) camera adopts the IMX462 1/2.8" monochrome sensor for Sony. The 2.9um pixel size accommodates a well depth of 12ke with a total of 2.1MP (the resolution is 1944*1096), and the diagonal is 6.46 mm.



Super AR Plus window
Mars-M II uses this super AR Plus window in front of it. This window glass can give super high transmittance from 310nm to 1100nm. With this important improvement, Mars-M II (IMX462) camera has a much better performance in ultraviolet and NIR.

Features:

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 1/2.8" sensor camera. All names will be engraved on the housing of the cameras.

Cutting-edge Design
The planetary camera 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.

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 you are taking solar photographs with prominence telescope, the Newton ring will be 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
Among planetary cameras in the world, this astronomy camera is the first ones to adopt the DDR3 cache. 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. But it still has an excellent performance even if it is connected to a USB 2.0 port.

DPS Technology
The planetary camera has DPS (Dead Pixel Suppression) technology. The DPS can analyze many dark frames to find out those fixed abnormal pixels and record the map in camera memory. In imaging, each exposure frame and those positions of dead pixels will be given a median value according to the active pixels around the abnormal pixels.


Over-voltage and Over-current Protection Mechanisms
The camera ensures the safety of your camera and other equipment through over-voltage and over-current protection mechanisms.

Data Port
When the camera is connected to the USB3.0 interface and a full-resolution preview is used, it can reach 136 FPS in RAW8 mode (10bit ADC). And the frame rate in RAW16 mode (12bit ADC) is 64 frames per second. When it is recording images, the actual writing speed will be affected by the writing speed of 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.

Readout Noise
Regarding readout noise, we solemnly promise that all values are obtained from actual tests. You can use the software for Sharpcap 4 to test. SC4 has a function called Sensor Analysis, providing a very simple way to test readout noise.


We wrote a tutorial on website: https://player-one-astronomy.com/service/manuals/

After many rigorous readout noise tests, the Mars-M II camera can reach a low readout noise of 0.73e at a gain of 350 and around 0.7e at a gain of 400.

If you are interested in readout noise testing, you can try it by yourself because it is very simple.

HCG Mode
The Mars-M II camera has a unique HCG mode, which will automatically turn on when the camera gain setting is ≥80. 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 Mars-M II camera is quite different from that of Mars-C. The sensitivity reaches its peak at 650-700nm, and very high QE is kept in infrared.

This is the relative QE curve provided by the company for Sony. The absolute QE peak is about 91%.
