Player One Astronomy Poseidon-C Pro (IMX571) Color Cooled Camera

NEW! Player One Astronomy Poseidon-C Pro (IMX571) Color Cooled Camera

Poseidon-C Pro (IMX571) cooled camera is developed by Player One Astronomy, it’s design for advanced DSO imaging. it adopts Sony IMX571 APS-C format color sensor. The 3.76um pixel size accommodates a well depth of 71.7Ke with a total of 26MP  (the resolution is 6252*4176), and the diagonal is 28.3mm.

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

Poseidon-C Pro (IMX571) cooled camera based on Sony STARVIS technology, it is back-illuminated pixel technology used in CMOS image sensors.

APS-C Format

Poseidon-C Pro cooled camera has APS-C format (23.5mm*15.7mm), this size is quite big for DSO imaging.

Native 16bit ADC

IMX571 sensor has native 16-bit on-chip ADC. Native 16bit ADC (65536 levels) provide higher sample resolution than 12bit (4096 levels) or 14bit (16384 levels). When we do non-linear transformation, 16bit data can endure very strong transform and also could bring much better light and dark transition, furthermore 16bit can make the color more vivid.

Non-Amp-Glow

Poseidon-C Pro cooled camera is a Non-Amp-Glow camera too!

300s dark frame at -20℃ of Poseidon-C Pro cooled camera(resize to 50%):

Non-Amp-Glow can give us very clean background, much easier to get high quaility images.

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 15fps 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

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

At gain=0, the camera has 14.26 stops dynamic range and 71.7Ke full well capacity, readout noise is 3.96e.

HCG open at gain=125, the camera has 13.58 stops dynamic range and 16.6Ke full well, readout noise drop to only 1.36e.

Frame rate

Poseidon-C Pro cooled camera can run 15FPS under RAW8 mode, that’s much faster than existing models on market.

Full well

Poseidon-C Pro cooled camera has 71.7Ke full well, it’s over 1.4 times than IMX571 Basic (50ke).

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.

Dark Current

The dark current is only 0.000105 e/s/pix at -20℃, and 0.001178e/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.
