Player One Astronomy guiding camera series, AKA Dwarf Planet Series, is design for guiding and imaging. This series including 3 sub-series, Ceres, Sedna and Xena.
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 well depth of 15ke with a total of 6.4MP (the resolution is 3096*2078), and the diagonal is 9mm.
Dwarf planet series integrated USB3.0 data port(500Mb/s), which can provide over 10 times speed than USB2.0 device(60Mb/s). Whatever you wants to do guiding or imaging, this camera series can handle it very well.
Dwarf planet camera diameter is 1.25″, it can slide in 1.25″ adapter of guiding scope, makes the whole setup shorter.
With a 5-100MM CS lens attached on the camera, it also can be used as a guider or finder.
The naming of Player One guiding cameras is interesting. Guiding camera is smaller than planetary camera, that’s why 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.
The guiding cameras developed by Player One Astronomy uses technological regular hexagon to construct the main body line.
The guiding 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.
When the camera is connected to the USB3.0 interface and 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. 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.
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.
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, you may try it yourself, which is very simple.
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.
