DESCRIPTION

New state-of-the-art design

The polygon as a regular hexagon is very Player One, Player one wants your camera to be as beautiful and practical as possible.

After much testing, Player one established the final style, which uses a scientific and technological octagon to build the main line of the body, complemented by round chamfers for both rigidity and flexibility.

The front piece is round to avoid diffraction in the RASA. The positive red, reminiscent of a summer fire, is combined with the subdued and stable black, and the ultra-thin glazing process on the entire surface gives the camera a luxurious and cool look, while maintaining the Player One style.

The Artemis-C Pro (IMX294) cooled camera is developed by Player One Astronomy and is designed for advanced deep sky image capture.
It adopts the 4/3″ Sony IMX294 4/3″ format color sensor. The pixel size of 4.63 um allows a well depth of 65.8 Ke with a total of 11.7 MP (resolution is 4144 x 2824) and the diagonal is 23.2 mm.

4-point tilting plate

When photographing deep sky objects, the use of the sensor tilt plate is now facilitated by the appearance of a 4-point adjustment that can be used from the back of the camera and not from the front as on many other brands' cameras.

The 4-point adjustment makes it easier to know which corner needs to be adjusted. An integrated high density sponge pad can block the light from side separation without any leakage.

To understand the 4-point adjustment method, we have made an example for users:

Cooling sensor

Player One series refrigerated chamber uses 2-stage TEC refrigeration unit, after improving the structure design to reject heat in the chamber chamber, Delta-T chamber can reach more than 40 ℃.

512MB DDR3 cache

As an improvement, the DDR3 cache of the cooled chambers has been increased to 512MB. It helps stabilize and secure data transmission, effectively prevents frame loss and significantly reduces read noise.

With the DDR3 cache, the camera no longer has high demands on computing requirements, it will still have excellent performance even when connected to a USB 2.0 port.

STARVIS technology

Artemis-C Pro (IMX294) cooled camera based on Sony's STARVIS technology, the back-illuminated pixel technology used in CMOS image sensors.

4/3 format

The Artemis-C Pro cooled camera has a 4/3″ format (19.2 mm * 13 mm), this size is very popular for Deep Sky imaging.

14-bit ADC

The IMX294 sensor has an on-chip 14-bit ADC. The 14 bits (16384 levels) provide higher sampling resolution than the 12 bits (4096 levels).

USB Type-C port

The rear of the cooled camera has 2 Type-C data ports and a 5.5 × 2.1 mm 12 VDC power port

The main data port supports USB3.0 protocol, the camera can run at 33 fps in RAW8 mode. The type C port is easier to connect when mounting the imaging equipment at night.

When recording images, since the actual writing speed will be affected by the writing speed of the hard disk itself, when the writing speed of the hard disk is slow, the recording may not reach the theoretical speed. It is recommended to use a high quality SSD for recording data to take full advantage of the camera's performance.

The camera has a 12V DC5.5*2.1mm port to provide sufficient power to the TEC cooling system. If you do not need to turn on the cooling, simply connect the main type C port, the camera will work as an uncooled camera.

Using standard cable

Anti-fogging cooling and heating system

In the ASCOM window, we provide 3 adjustable parameters: target temperature, fan speed and anti-fogging power.

Delta-T standard: 40 ℃ (±2 ℃), when ambient temperature is 30 ℃, fan speed 100%, superheat 0%.

Recommended Delta-T settings: 35 ℃ below ambient temperature, fan speed 70%, superheat 10%, power consumption 40-60%.

Cooling fan speed is also adjustable, default value is 70% speed.

Fog problem is the biggest enemy of astro image, the camera has integrated anti-fog heater in front of the camera. The heating power is adjustable.

Over-voltage and over-current protection mechanism

Player One cameras ensure the safety of your camera and other equipment with overvoltage and overcurrent protection mechanisms.

Performance

At gain=0, the camera has a dynamic range of 13 stops and a full well capability of 65.8 Ke, read noise is 7.8e.

HCG opens at gain=120, the camera has a dynamic range of 12.97 stops and 14.5Ke, read noise drops to only 1.8e.

Frames per second

The Artemis-C Pro cooled camera can run at 33 frames per second in RAW8 mode, much faster than existing models on the market.

Playback noise

As for reproduction noise, we solemnly promise that all values are obtained from real tests. And for users, Sharpcap 4 can be used for testing. SC4 has a function called Sensor Analysis, which provides a very simple way to check read noise.

Player one writes a tutorial on our site: https://player-one-astronomy.com/service/manuals/
If you are interested in testing playback noise, you can do it yourself, which is very simple.

Image by Dark

Here is a Dark from the Artemis-C PRO, Gain = 0, Offset = 5, Exposure = 300 s, Temp = -20 ℃

Dark Current

The dark current is only 0.0015 e/s/pix at -20℃ and 0.0086e/s/pix at 0℃. In the whole curve, the dark current looks almost like a straight line, which can prove that the Artemis camera is of very good quality.

EQ curve

This is Sony's Relative QE curve, we estimate the peak QE of the IMX294 to be around 75%.
