Visit Xena 585M is the latest guidance camera developed by Player One. It is part of the Dwarf Planet Series, a range designed for both high-precision guidance and astronomical imaging. This series comprises three models - Ceres, Sedna and Xena - whose sensor size is directly linked to the name of the dwarf planet engraved on the case.
With its modern Sony IMX585 sensor in 1/1.2″ format, the Xena 585M is positioned as a top-of-the-range model in the world of guiding cameras, offering exceptional sensitivity, extremely low read noise and remarkable versatility.
The Xena 585M is equipped with Sony IMX585 monochrome sensor, a latest-generation CMOS sensor in 1/1.2″. It proposes a resolution of 8.3 megapixels (3856 × 2180) with 2.9 µm. This combination ensures excellent sampling both for precise guidance and for deep-sky or planetary imaging.
Thanks to a well depth of 47 ke- and a diagonal of 12.85 mm, With its high dynamic range and excellent tolerance of bright stars, the camera is the ideal solution for all kinds of applications.
The IMX585 sensor is based on the latest technology STARVIS 2 from Sony. This is CMOS technology with backlit pixels (BSI), designed to maximize sensitivity and reduce readout noise. This architecture considerably enhances low-light performance, a decisive advantage for faint star guidance and deep-sky imaging.
The Xena 585M features a HDR (High Dynamic Range) mode, mode, a feature specific to cameras based on the IMX585 sensor. This mode increases dynamic range while further reducing read noise, making it easier to capture fine structures in deep-sky objects, even in the presence of strong contrasts.
Like all cameras in the Dwarf Planet Series, the Xena 585M is equipped with a USB 3.0 port (5 Gbps), with transfer speeds more than ten times faster than USB 2.0. In full-resolution preview mode, the camera can achieve up to 47 frames per second in RAW8 mode (10-bit ADC).
To take full advantage of this performance, the use of a High-quality SSDs is recommended, as the writing speed of the storage medium may limit the actual recording throughput.
The Xena 585M adopts a 1.25″ mechanical diameter, This allows it to fit directly into a standard 31.75 mm eyepiece holder or guide finder. This compact format reduces the length of the optical train and facilitates integration into lightweight or nomadic configurations.
Combined with a CS lens from 5 to 100 mm (optional), the camera can also be used as a autonomous guidance camera or electronic finder.
Xena 585M benefits from proprietary technology DPS (Dead Pixel Suppression). The system analyzes numerous dark images to identify fixed defective pixels and stores their position in the camera's internal memory. Each time a picture is taken, these pixels are automatically corrected by interpolation from neighboring pixels, without any external software intervention.
To guarantee the longevity of the camera and the safety of all your equipment, Player One Astronomy has integrated the following features overvoltage and overcurrent protection. These devices protect the camera in both fixed and mobile environments.
The performance of the Xena 585M is based on actual tests. Reading noise can be as low as 0.7 electron at a gain of 500. Users can check these values themselves using the Sensor Analysis from SharpCap 4.
The camera also displays a maximum quantum efficiency (QE) of around 91 %, This guarantees excellent sensitivity over a wide spectral range.
The Xena 585M can be used for software guidance (pulse guiding) or via a ST4 direct connection. Simply connect the camera to the AUTO GUIDE of the equatorial mount using an ST4 cable for reliable, autonomous guidance.
