Description

QHY 5-III-715C Color Astronomy Camera is an ultra-high resolution back-illuminated color camera with extremely low read noise. The sensor has a 1/2.8-inch optical format, similar to the QHY5III462C. However, the QHY5III715C has 4X as many pixels as the QHY5III462C for 4K resolution with 1.45um pixels in a 3830 x 2160 array. This makes the new QHY5III715C ideal for smaller short focal length refractors. The exceptionally small pixels subtend a FOV of less than 1 arcsecond at focal lengths of 12 inches (300mm) or longer. The QHY5III715C inherits all of the updates and improvements of the QHY5III Series Ver. 2 line of cameras.

Extended Near Infrared Sensitivity

Also similar to the QHY5III462, the new QHY5III715C has extended NIR spectral sensitivity. In this latest generation of sensors, the photodiodes are 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.

New QHY5III V.2 Models

As the fourth in the latest QHY5III series V.2 planetary cameras and guiders, the QHY5III715C includes all of the improvements and upgrades found in this latest series of cameras, including:

Larger 512MB DDR3 image buffer
Improved front end design
CS and C-mount lens compatibility
USB 3.2 Type C interface
Universal ST-4 guiding port
Status indicator LED
1.25” body size for maximum compatibility
