QHY 5III585M Planetary Camera with High Near Infrared Response QHY5III585M is an QHY5III V2 series planetary and guiding camera with the Sony IMX585 sensor, which is an enhanced version of the IMX485. It has a high sensitivity in the near-infrared and the dynamic range performance has been greatly improved. It has a 1/1.2-inch large sensor and zero amp glow. The sensor also has a larger full well capacity of over 50ke-, more than three times that of the previous generation IMX585 sensor. The QHY 5III585M comes with both an IR blocking filter and IR850 filter. The IMX585 sensor is 11.2mm x 6.3mm in size. As an example, a telescope with 650mm focal length will fit the full disk of the Sun or Moon. The QHY 5III585M inherits all of the updates and improvements of the QHY5III Series Ver. 2 line of cameras, as follows: 512MB DDR3 memory Front end design with better compatibility USB 3.2 Gen1 Type C Interface Universal Guiding Interface Indicator LED In this latest generation of sensors, the photodiode portion of the pixel well is physically deeper than in previous sensors, allowing photons of longer wavelengths to penetrate deeper into the substrate. This dramatically increases the sensor’s sensitivity to red and near-infrared (NIR) light. The sensor displays almost equal peak sensitivity to NIR light as it does to light in the visible spectrum. The IMX585 is a Sony Starvis II processor that enables high sensitivity and high dynamic range (HDR). It also improves sensitivity in the near-infrared range compared to the IMX485.
