QHY5III200M (Ver.2)

Introduction

The QHY5III200M is one the first new 2nd generation QHY5III Series planetary cameras and guiders. It is also the first mono CMOS planetary camera with high near-infrared enhancement (similar to that of the QHY5III462C and new QHY5III585C) that QHY has developed. In addition, the 4um pixel size makes it an excellent choice for guiding. The camera includes an unblocked AR coated filter and an IR850 filter. New QHY5III v.2 Models As one of the first new 2nd generation of planetary cameras and guiders, the QHY5III200M 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 New Monochrome CMOS Sensor with High NIR

The QHY5III200M uses a new mono CMOS sensor with very high QE in the near IR range from 700nm to 1000nm. This includes the important methane absorption line at 890nm. Methane is an important absorber in the atmosphere of Jupiter and the other gas giants of our solar system and imaging in this band can reveal unique details and their altitude in the atmosphere. Until now, this extended NIR sensitivity was available mainly in Sony’s 6th generation of color CMOS sensors. However, serious planetary imagers often prefer to use a monochrome camera and dedicated RGB + Methane filters. Now that option is available at a very reasonable price point.
