QHY 165 Coldmos Cooled Color CMOS Camera

The QHY 165 Coldmos Cooled Color CMOS Camera is a APS-C, 16 Megapixel fron-illuminated Color CMOS camera.The pixel size is 4.8um, yielding high-resolution with modest size telescopes. The camera is capable of producing 10FPS@16-Megapixels. It has a two-stage TEC that cools the sensor to -35C below ambient. The ADC is 12-bit with 3.2e- read noise! 

The QHY165M has a 128MB DDR Memory Buffer. A QHY183M 16-bit image is about 40MB, so 128MB of memory can easily buffer a full frame for transfer to the computer using QHY183M software with native single-frame shooting function, instead of intercepting a frame from a continuous video transmission. This makes data transfer to the computer stable and reliable because there is no USB bandwidth or busy CPU problems.

The QHY165M utilizes the Anti-Dew features common to the QHY COLDMOS cameras. A heated optical window prevents exterior dew from forming, and the CMOS chamber has a desiccant plug socket to prevent moisture from forming on the sensor at cold temperatures.

The QHY165M incorporates QHY’s Anti-Amp Glow technology to significantly reduce typical CMOS amplifier glow to a minimum, allowing excellent calibration by subtracting a dark frame.

  • Anti-dew heater to eliminate condensation and ice buildup
  • Anti-amp glow circuit to reduce long exposure amp glow
  • 128MB DDR memory to speed up download times
