QHY5III678C, the upgraded V2 version of QHY5III178C, is a new planetary and guiding camera with excellent near-infrared high sensitivity. The 678C comes with an IR850 filter.
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 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.
The back focus length (BFL) of the 5III V2 camera is only 8mm, which means you can easily use a V2 cam with your OAG. The basic top adapter includes 1.25 inch threads so you can still use your 1.25 inch filter.
The top adapter glass of V2 can be easily switched out. You can add a 1.25" CS adapter to connect a CS lens, or add a second CS-C lens for C-mount lens. The two adapters are all standard accessories of V2 cams.
USB3.2 Gen 1 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.
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.
