QHY 5-III 678 MONO - USB3.0 CMOS Camera - D= 8.9 mm sensor

Astrolumina Alccd-QHY 5III 678 - fast monochrome CMOS Camera

The ALccd-QHY 5III 678 is, from the III rock USB3.0 series, the model with the smallest pixels. It is ideal for short focal length optical systems and highest resolution. It is an excellent camera for the solar, lunar, planetary and meteor photography, but also a low-noise and highly sensitive camera for deep sky photography.

Sensor and shutter

In the ALccd-QHY 5III 678, the built-in sensor works in "rolling shutter" mode. The STARVIS back-illuminated sensor technology allows the highest sensitivity and quantum efficiency in the visible and infrared range of light.

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.

Body

The housing shape is designed so that the camera, like the proven ALccd-QHY 5-II models, fits into standard 1.25" focusers or adapters. The fins provide for a fast and selective dissipation of the heat which is produced during the exposure.

512 MB DDR3

The QHY5III (Ver. 2) series planetary and guiding cameras are all equipped with a 512 MB 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 256 MB, for example.

In comparison, the 512 MB 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. All V2 cams in the future share these features.

The BFL of V2 cam is only 8 mm, which means you can easily compat 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 a lens! You can add a 1.25inch-cs adapter to connect CS lens, or add a CS-C adapter for C-mount lens. The two adapters are all standard accessories of V2 cams.

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.


The ALccd-QHY 5III 678 camera is also available as color version. Please contact us.


System requirements

The camera has an advanced electronics that makes a PC with USB 2.0 support necessary. The maximum performance can be reached only with a powerful USB 3.0 computer.

The operating software is Windows 7, 8 and 10 compatible and supported by 32- and 64-bit.

We recommend the ASCOM compatible software packages MSB AstroArt, PHD or MaxIm DL for the Autoguiding. For shooting the freeware SharpCap.
