QHY183 M/C – Cooled Medium Size CMOS Cameras

The QHYCCD medium size COLDMOS camera series includes all of the cooled cameras with CMOS sensor sizes from less than 1 inch to Full Frame 35mm Format (QHY128C und QHY367C and QHY410C)and includes BSI (back-illuminated) as well as FSI (front-illuminated) CMOS sensors in both monochrome and color cameras.

  • USB 3.0
  • Front-illuminated and Back-illuminated Sensors
  • Lightweight Compact Design
  • Regulated TE Cooling Delta -35C to -40C
  • 128 MB DDR Frame Buffer
  • ST-4 Compatible Guide Port
  • Filter Wheel Port
  • Anti-Noise Technology
  • Anti-Amp Glow Technology
  • Anti-Dew Technology

All models include a heated optical window to prevent external dew, a desiccant plug socket to help maintain a frost-free CMOS chamber, a 128MB frame buffer, a filter wheel port, and 2-stage TE cooling to reduce the sensor temperature to -35C or -40C below ambient along with temperature regulation to maintain a constant temperature set point. Due to the efficient TE cooling, single exposures many minutes in duration are possible, making them ideally suited for deep space imaging of dim objects as well as brighter objects and planets.

The QHY camera has a built-in 128MB DDRII image buffer. The benefit of the image buffer is that the memory will cache the image and transfer it to the computer when the USB interface is not busy or being interrupted, and the frame will not be lost or corrupted. This buffer also allows a slower computer with USB 2.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals. This buffer also helps multiple camera applications and avoids USB transfer problems. For example, it is possible to operate four QHY163M cameras on the same computer to create an LRGB imaging array.

The models (QHY183M/C, QHY294C) use a Sony STARVIS Exmore R back-illuminated sensor. STARVIS is Sony’s designation for sensors capable of recording under starlight. These back-illuminated sensors have even greater sensitivity as well as noise reduction - the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. They retain the advantages of CMOS image sensors such as low power consumption and high-speed operation while dramatically improving sensitivity.

Front and Back Illuminated Structure

Further details about the QHY183M/C can be found on the webpage of QHYCCD

The QHY183M/C is 20 Megapixel back-illuminated CMOS camera with a peak QE of 84%. The sensor size is 13.3mm x 8.87mm (diagonal 15.8 mm) and the pixel size is 2.4um, yielding high-resolution with modest size telescopes. The camera is capable of producing 15FPS@20 Megapixels. It has a two-stage TEC that cools the sensor to -40C to -45C below ambient. The ADC is 12-bit / 16-bit with 1e- read noise! The computer interface is USB 3.0 and exposure times can be set from 50us to 3600sec.The camera is also available in color version.

QHY 183c
Nach der kompetenten Beantwortung diverser Fragen durch Ihre Mitarbeiter habe ich mich für diese Kamera entschieden.
Ich verwende die Kamera ohne Guiding mit der Software Sharpcap für die Aufnahmen von Deepsky Objekten und Planeten. Bisher hatte ich keine großen Probleme damit.
Die Installation erforderte allerdings ein paar Anläufe, da die Beschreibung nicht perfekt ist.
  • Kurze Belichtungszeiten (weniger als 45s) reichen bereits aus um farbige Bilder zu sehen.
  • Die Instationsbeschreibung von QHY ist teilweise verwirrend. Die Sharpcap Einstellungen sollten klarer beschrieben werden.
Vielen Dank für Ihr Feedback. Wir haben bereits QHY kontaktiert, dass die Software-Beschreibungen teilweise nicht eindeutig sind. Der Hersteller wird daran arbeiten
