Player One Xena-M (IMX585) USB3.0 Mono Guiding Camera
The Player One Xena 585M is a “small camera, big sensor” guider that also pulls double duty for lightweight imaging. Built around the Sony IMX585 mono sensor (1/1.2"), it combines modern STARVIS 2 back-illuminated tech, USB 3.0 speed, and genuinely strong performance specs—so you get fast downloads, clean stars, and a wide enough field to make finding guide stars way less annoying.
Sony IMX585 mono sensor (1/1.2") for a wide guide field and easier star acquisition
8.3MP resolution (3856 × 2180) with a 12.85mm diagonal—roomy for guiding and flexible for imaging
2.9µm pixels with a deep 47ke full well for strong dynamic range headroom
STARVIS 2 back-illuminated sensor tech for improved sensitivity and low-light performance
USB 3.0 (5Gbps) integrated data port for fast transfers (a big jump over USB 2.0)
1.25" body diameter slides straight into a 1.25" guide scope adapter to keep spacing short and clean
HDR mode (IMX585 feature) for expanded dynamic range and lower read noise—helpful when you’re also using it for DSO imaging
DPS (Dead Pixel Suppression) maps and corrects fixed bad pixels using camera-stored calibration data (built from dark frame analysis)
Overvoltage & overcurrent protection helps protect the camera and the rest of your rig
ST4 guiding support: connect to your mount’s AUTO GUIDE port for direct guiding
Speed note: up to 47 FPS at full resolution in RAW8 preview (10-bit ADC). For recording, an SSD is recommended to sustain high write speeds.
Performance you can actually quantify: tested read noise down to 0.7e at gain 500
High sensitivity: approx. 91% peak QE (per published curve)
