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.

Hervorragende Ergebnisse mit der QHY678mono Kamera
Die QHY678mono konnte ich bisher ausgiebig testen und bin mehr als begeistert. Auch wenn die Pixelgröße nicht zu meinem H-Alpha Setup passt, so ist doch die Downloadrate auf den Zwischenspeicher enorm. In der ersten Sekunde werden gefühlte 300 Bilder "mal eben so" zwischengespeichert, sodass man doch beeindruckende Ergebnisse einfangen kann ! Die Kamera übertrifft meine Erwartungen, auch wenn die Chipgröße arg klein ist. Eine kleine double Stack Aufnahme im Anhang. Ein Mosaik aus 12 Einzelbilder und einer 3fach Telezentrik in Kombination mit der QHY678mono. Bild invertiert und eingefärbt. Vielen Dank. Bengt Lindqvist
