QHY 5-III-678 M/C Guiding- and Planetary Camera
The QHY 5-III-678 M/C is the latest evolution of version 2 of the QHY 5III series of planetary and guiding cameras. The QHY 5-III-678 M/C can be considered an improved version of its earlier, the QHY 5-III-178M CMOS Camera (#1931024 , € 375) .
Like the Sony IMX 178, Sony's new IMX 678 sensor is a 1/1.8-inch back illuminated (BSI) sensor. However, compared to the IMX 178, it has higher resolution (smaller pixels) and higher QE, as well as increased sensitivity in the near-infrared (NIR) spectral range. In addition, the QHY 5-III-678 M/C camera modules have some improved features such as:
- Larger internal image memory DDR 512MB
- Improved front and end design
- Compatibility with CS and C-mount lenses
- More stable and faster USB 3.2 Type-C interface
- Universal ST-4 guiding port
- Control LED for status indication.
The new QHY 5-III-678 M/C has an interesting new feature, a unscrewable M 28.5 filter holder with built-in 12.5mm (1/2") UV/IR blocking filter.
Removing this retaining ring along with the built-in 1/2" filter allows all standard 1 1/4" filter be screwed on instead. This allows interesting applications for image acquisition from UV to far into the NIR range.
At the same time, however, the 1/2" filter standard also offers further possibilities for using other types of filters that are common in industry.
We describe more detailed information about these features here.
