Player One Astronomy guiding camera series, AKA Dwarf Planet Series, is designed for guiding and imaging—this series includes 3 sub-series, Ceres, Sedna, and Xena.
Product Description
Sedna-M is a guiding camera developed by Player One Astronomy, which adopts the Sony IMX178 1/1.8” format sensor. The 2.4um pixel size accommodates a good depth of 15ke with a total of 6.4MP (the resolution is 3096*2078), and the diagonal is 9mm.
Highlights
Dwarf planet series integrated USB3.0 data port(500Mb/s), which can provide over 10 times faster than USB2.0 device(60Mb/s). Whatever you want to do guiding or imaging, this camera series can handle it very well.
Dwarf planet camera diameter is 1.25″, it can slide in a 1.25″ adapter of guiding scope, making the whole setup shorter.
A 5-100MM CS lens attached to the camera can also be used as a guide or finder.
Features:
The naming of Player One guiding cameras is interesting. The guiding camera is smaller than the planetary camera, so we choose dwarf planets to name it.
The size of each dwarf planet to a certain extent represents the size of camera sensors. We will name Ceres with a 1/3″ sensor camera, and for Xena, we will name it with a 1/1.2 inch sensor camera. All names will be engraved on the housing of the cameras.

Cutting-edge Design
The guiding cameras developed by Player One Astronomy use a regular hexagon to construct the main body line.
DPS technology
The guiding cameras from Player One Astronomy have DPS (Dead Pixel Suppression) technology. The DPS analyzes many dark frames to find those fixed abnormal pixels and record the map in camera memory. In imaging, in each exposure frame, the 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 ensure the safety of your camera and other equipment through overvoltage and overcurrent protection mechanisms.
Data Port
When the camera is connected to the USB 3.0 interface and a full-resolution preview is used, it can reach 60 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. You should use a high-quality solid-state drive to record data to give full play to the camera's performance.
Use the ST4 guide cable to connect the camera and the AUTO GUIDE port of the equatorial mount to do the guiding.
Performance
Readout Noise
Regarding readout noise, we 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, which provides an effortless way to test readout noise.
Player One wrote a tutorial on their website: https://player-one-astronomy.com/service/manuals/
After many rigorous readout noise tests, the Sedna-M camera can reach a low readout noise of 1.34e at a gain of 350.
If you are interested in readout noise testing, try it yourself, which is very simple.
QE Curve
HCG Mode
The Sedna-M camera has a unique HCG mode, which will automatically turn on when the camera gain setting is >30. The HCG mode can greatly reduce the readout noise and retain the same high dynamic range as the low gain.
