Mars-C II USB3.0 Color Camera (IMX662)

Mars-C II (IMX662) is a planetary camera developed by Player One Astronomy, which adopts the newest Sony IMX662 1/2.8” format sensor. The 2.9um pixel size accommodates a well depth of 39ke with a total of 2.1MP  (the resolution is 1936*1100), and the diagonal is 6.44 mm.

STARVIS 2 Technology

Mars-C II (IMX662) and Uranus-C (IMX585) based on Sony newest STARVIS 2 technology, it is back-illuminated pixel technology used in CMOS image sensors.

Format

Mars-C II (IMX662) has 1/2.8″ format, this size is quite suitable for planetary imaging

FullWell

Mars-C II (IMX662) has 39Ke full well, it’s almost 3 times than IMX462 (13Ke).

Non-Amp-Glow

Biggest supprise of Mars-C II (IMX662) camera is, its dark frame is totally “dark”, whatever we strength the curve, there is no AMP glow at all!
Non-Amp-Glow can give us very clean background, much easier to get high quaility images. Mars-C II camera also very good for lunar and planetary imaging

2nd Gen – Sensor Tilt Plate

When taking deepsky objects, using sensor tilt plate can get a much smaller field curvature of the telescope. The built-in high-density sponge shading pad can block the light from the side slits without any side leakage.

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 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 107 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.

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.

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