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.

QHY5III (Ver. 2) series cameras have adopted a new front-end design with better compatibility. The new front end supports 1.25″ interface of telescopes and is also compatible with CS-port lenses and C-port lenses, and can shoot with C/CS-port lenses with filters attached.

A 1.25″ framed filter can be fitted with the front end, and a frameless filter can be fitted on the front part of the upper CMOS. The size of the filter glass that is compatible here varies depending on the size of the sensor, but is basically a standard lab filter specification. Compared to the more expensive astronomical filters, lab filters tend to be less expensive and have a wider variety of bands, allowing you to develop more uses and applications for them.

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.

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.

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.
