Equipped with a sensitive 1/2.8-inch CMOS sensor and a resolution of 5.6 megapixels, the QHY5III585C provides exceptional sensitivity and low noise performance, resulting in crisp and vibrant images. Its USB 3.0 interface ensures fast data transfer, enabling quick and efficient image capture. With its compact and lightweight design, this camera offers convenience and portability, making it an ideal choice for astrophotography on the go. Whether you're an avid astronomer or a seasoned astrophotographer, the QHY5III585C Planetary Camera is the perfect tool to elevate your imaging capabilities and unlock the wonders of the night sky.

QHY5III585C is a new generation of QHY5III V2 series planetary guide camera, which is an enhanced version of its predecessor QHY5III485C. It has a high sensitivity in the near infrared similar to that of 5III462C, while the dynamic range performance has been greatly improved. It has a 1/1.2-inch large sensor and excellent characteristics of zero glow.

The product comes with filters including an IR850nm filter.

Extended Near Infrared Sensitivity

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.

BSI

One benefit of the back-illuminated CMOS structure is improved full well capacity. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor.

In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.

Enhanced Dynamic Range

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 by approximately 1.7 times* compared to the IMX485. The new camera QHY5III585C has a large fullwell capacity of over 30ke-, approximately three times that of the previous generation QHY5III485C.

512MB DDR3

The QHY5III (Ver. 2) series planetary and guiding cameras are all equipped with a 512MB DDR3 image buffer which can effectively reduce the pressure on computer transmission, a great help for planetary photography which often requires writing a large amount of data in a short period of time. Some deep-sky astrophotography cameras on the market today only have 256MB, for example.

In comparison, the 512MB DDR3 memory of the new 5III (Ver. 2) series cameras represents a significant upgrade.

New Front-end Design with Better Compatibility

QHY5III (Ver. 2) series cameras have adopted a new front-end design with better compatibility. Here we only take QHY5III200M as example, however, ALL V2 cams in the future share these features.

The BFL of V2 cam is only 8mm, which means you can easily compact a V2 cam with your OAG. The basic top adapter includes 1.25 inch threads and you can still use your 1.25 inch filter.

The top adapter glass of V2 can be easily switched. One of the advantage of changeable top glasses is you can use one filter even you’re using Lens! You can add a 1.25inch-cs adapter to connect CS lens, or add a second CS-C lens for C-mount lens. The two adapters are all standard accessories of V2 cams.

By the way, there’s a 1.25 inch filter wheel adapter to connect your mono planetary cam with QHYCFW3-S filter wheel.

USB 3.2 Gen1 Type C Interface

The new QHY5III (Ver.2) series cameras all use the USB3.2 Gen1 Type-C interface. Compared to the USB3.0 Type-B interface used in the previous generation, the Type-C interface has a longer life and is more flexible.

Tips: It is recommended to use the official standard Type-C data cable of QHYCCD. As the market is flooded with a large number of poor-quality Type-C cables, casual use may lead to the camera malfunctioning. If you use your own spare cable, please make sure it is a high-quality cable.

Universal Guiding Interface

The custom interfaces of the previous generation of planetary cameras and guiders has been replaced in the QHY5III (Ver.2) cameras with a more universal ST-4 compatible guiding interface. Now, even if the guiding cable is lost or damaged, you will be able to easily get a replacement on the market at a low cost.

Indicator LED

The new QHY5III (Ver.2) series of cameras is equipped with a status indicator at the back of the camera. If the camera experiences an abnormal status, the multi-colored indicator light will help to determine the situation with different colors signifying different conditions. During normal operation this indicator light is off, so there is no worry about light contaminating the image.
