Product description

Saturn-M SQR and Saturn-C SQR are the most powerful planetary cameras in our history! Based on IMX533 BSI sensor, high image quality, high resolution and square format, non-amp-glow feature, the camera will be great for lunar, solar mosaic and DSO lucky imaging.

Product Description

Saturn-M SQR (IMX533) camera is developed by Player One Astronomy, SQR means its sensor is square. Saturn-M SQR camera, which adopts Sony IMX533 1” square format monochrome sensor. The 3.76um pixel size accommodates a well depth of 73Ke with a total of 9MP (the resolution is 3008*3008), and the diagonal is 16mm.

STARVIS Technology

Saturn-M SQR (IMX533) camera based on Sony STARVIS technology, it is back-illuminated pixel technology used in CMOS image sensors.


Saturn-M SQR camera has 1″ format, this size is quite big for imaging.

Extend Full well Capacity

Based on our technology, we improved the full well of Saturn-M SQR camera to 73Ke , it’s almost 1.5 times than IMX533 Basic (50ke).

High Frame rate

Based on our technology Saturn-M SQR camera can run 43FPS under RAW8 mode, that’s much faster than existing models on market.

Dual Sampling Mode

Saturn SQR series has dual sampling mode. Nromal mode and LRN mode, they has different advantages in imaging.

1. Normal mode has faster FPS, it is more suitable for planetary imaging.

2. LRN (low readout noise) mode has lower readout noise and higher dynamic range. it is more suitable for DSO lucky imaging.



Dark frame of Saturn SQR (IMX533) camera is totally “dark”, that’s we called it “Non-Amp-Glow” camera!

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

Recommended accessories:

ACS (Active Cooling System) is a external air-cooled system, designed for solar and big format planetary cameras which already has PCS (Passive Cooling System).

ACS can provide much better temperature control. When camera has PCS + ACS, temperature is only 7℃ higher than ambient, camera body is a little warm but won’t hot!

ACS is not only can be used in daylight for solar imaging, it also could be used in night for DSO lucky imaging.

Saturn SQR camera also very good for lunar and planetary imaging, its 1″ big format and 9MP total pixels, easier to capture full disk of the Moon and the Sun, or make mosaic more efficient.


The naming of Player One Astronomy cameras is unique. Planetary camera line, naming depend on the size of planets, Mars(1/3″), Neptune(1/2″), Uranus(1/1.2″), Saturn(1″), Jupiter(4/3″).

Cutting-edge Design

The planetary cameras developed by Player One Astronomy 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 orange, which is imply solar, 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, can’t take my eyes off

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.

Passive Cooling System

Player One add a new feature called Passive Cooling System to conduct the heat from the sensor out.

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 43 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.


HCG open at gain=125. Saturn SQR series has dual sampling mode, Normal mode has faster fps, LRN (low readout noise) mode has lower readout noise and higher dynamic range.

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:

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