From the website: The ZWO ASI290MM USB3.0 Monochrome Astronomy Camera makes for a budget-friendly planetary and guide camera. Compared to the ASI120MM, the ZWO ASI290MM utilises a back-illuminated IMX290 Sensor and features a larger resolution at 1936*1096, small pixel size of 2.9um and much faster frame rate at 170FPS which makes it significantly superior for planetary imaging. The IMX290 Sensor is back-illuminated to improve image quality at lower illumination.
This camera is in excellent condition. Comes with original box and driver disc. See pics.
