Caméra ARTEMIS-M Pro refroidie IMX492

DSO cooled camera line is the most advanced product line in Player One history. We start the project from 2021, through a lot of modify and rebuild we made this final version. It brings our newest technology and design to everyone, we are very proud to introduce this camera line.

Power supply is not include in camera package, high quality 12V 5A power supply link: https://player-one-astronomy.com/product/12v-5a-power-supply-dc5-5-x-2-1mm/

Product Description

New Cutting-edge Design

Polygon like regular hexagon is very Player One, the DSO cooled cameras we want to make it more beautiful and practical. After a lot of trying,  we fix the final style, which uses a scientific and technological octagon to construct the main body line and 4 sides are cambered surface, supplemented by round chamfers to achieve both rigidity and flexibility.

The front piece is round to avoid diffraction on RASA. 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, and keep Player One style.

Artemis-M Pro (IMX571) cooled camera is developed by Player One Astronomy, it’s design for advanced DSO imaging. it adopts Sony IMX492 4/3″ format monochrome sensor. The 2.315um pixel size accommodates a well depth of 18.6Ke with a total of 48MP  (the resolution is 8288*5648), and the diagonal is 23.2mm.

Rear Adjustment 4 Point Sensor Tilt Plate

When taking deepsky objects, using sensor tilt plate can get a much smaller field curvature of the telescope. We adopts rear Adjustment and 4 point tilt plate, it has a lot advantages in usage.

4 Point adjustment is easier to know which corner is needed to adjust. The built-in high-density sponge shading pad can block the light from the side slits without any side leakage.

For understand 4 point adjustment method, we made a example for users:

Deep Cooling

Player One cooled camera series use 2 Stage TEC Cooling unit, after improved the structure design to reject the heat back to camera chamber, Camera Delta-T can reach over 40℃.

512MB DDR3 Cache

As an improvement, DDR3 cache in cooled cameras are increased to 512MB. It helps stabilize and secure data transmission, it effectively avoids frame dropping and greatly reduces readout noise.

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.

STARVIS Technology

Artemis-M Pro (IMX492) cooled camera based on Sony STARVIS technology, it is back-illuminated pixel technology used in CMOS image sensors.

4/3″ Format

Artemis-M Pro cooled camera has 4/3″ format (19.2mm*13mm), this size is very popular for DSO imaging.

Pixel BIN mode

IMX492 sensor has native 48 Mega pixel, no need to unlock anything and don’t need any technology to do that. After you know this, following description will be very easy to understand.

12bit depth: IMX492 has 12bit on-chip ADC. When use BIN1 mode, IMX492 has 48Mega pixels, pixel size is 2.315um, and bit depth is 12bit (4096 levels).

14bit depth: When use hardware BIN2 mode, IMX492 will has 11.7Mega pixels, pixel size is 4.63um, and bit depth extend to 14bit (16384 levels) .

BIN1 and BIN2 also will cause the full well, FPS and readout noise be changed.

Software BIN support BIN2, BIN3 and BIN4 mode (and we provide Sum BIN and Average BIN), but Hardware BIN only has BIN2 mode (Sum BIN).

Type-C Data port and Power port

Back piece of cooled camera has 2 Type-C data port and 12V DC 5.5×2.1mm power port.

Main data port support USB3.0 protocol, the camera can run 8fps under RAW8 mode. Type-C port is easier to plug in when assemble the imaging equipment in night.

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.

The camera has 12V DC5.5*2.1mm port to provide enough power to TEC cooling system. If you don’t need to power up cooling, only need to connect the main Type-C port, the camera will works as a uncooled camera.

Standard Cable Usage

Cooling System and Anti-Dew Heater

In ASCOM window, we provide 3 adjustable parameters: Target temperature, Fan Speed and Anti-Dew power.

Standard Delta-T: 40℃ (±2℃) , when ambient temp 30℃, fan speed 100%, dew heater 0%.

Recommend Delta-T settings: 35℃ below ambient, fan speed 70%, dew heater 10%, power consumption 40- 60%.

The rotation speed of cooling fan is also adjustable, the default value is 70% speed.

Dew problem is the biggest enemy in astro imaging, the camera integrated anti-dew heater in front of the camera. The heat power is adjustable.

Overvoltage and overcurrent protection mechanism

Player One cameras produced by us ensures the safety of your camera and other equipment through overvoltage and overcurrent protection mechanisms.

Performance

Hardware BIN2 mode:

At gain=0, the camera has 13 stops dynamic range and 65.8Ke full well capacity, readout noise is 7.8e.

HCG open at gain=120, the camera has 12.97 stops dynamic range and 14.5Ke full well, readout noise drop to only 1.8e.

BIN1 mode

in BIN1 mode, Artemis-M PRO start with Gain 110.

Frame rate

Under RAW8 mode, Artemis-M Pro cooled camera can run 33FPS @ Hardware BIN2 mode and 8FPS @BIN1 mode.

That’s much faster than existing models on market.

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: https://player-one-astronomy.com/service/manuals/

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

Dark Frame

We provide an original dark frame of Artemis-M PRO camera, Gain=0, offset=5, exposure=300s, Temp=-20℃: Download Dark frame

Dark Current

The dark current is only 0.0004 e/s/pix at -20℃, and 0.0021e/s/pix at 0℃. In entire curve, dark current is almost like a straght a line, which can prove that Poseidon camera has very good quality.
