QHY 183C Cooled Color Astronomy Camera
The 20-megapixel QHY183C camera uses the back-illuminated Exmor R Sony IMX183 20MP sensor for high sensitivity and a quantum efficiency of 84%. The 1-inch color sensor has an array of 5544x3694 pixels that are 2.4um in size, with readout noise as low as 1e and a full well depth of 15.5ke-. This CMOS astrophotography camera is capable of 4K video output at 31fps and full resolution real time output at 19 frames per second. Ideal for serious deep-sky imagers!
The QHY183C color camera comes with a two-stage TEC cooling and temperature control that cools the camera as low as -45C below ambient, which is ideal for warm and damp summer observing conditions. QHY has also built in anti-dew technology into the QHY183. The sensor chamber is sealed and incorporates a silicon gel tube socket and heater to help keep both the sensor and the sensor window dry.
The QHY183C 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 QHY183 cameras on the same computer to create an LRGB imaging array.
The QHY183C camera has a control circuit to reduce amplifier glow significantly, especially important for longer exposures of deep-sky objects at high gain.
• QHY183C cooled 20-Megapixel color astronomy camera ideal for serious deep-sky imaging
• Sony STARVIS Exmor-R IMX183 1-inch CMOS sensor with small 2.4um pixels in a 5544x3694 array
• Two-stage cooling keeps sensor temperature as much as 45C below ambient for low-noise imaging, even in warm conditions
• 128MB DDRII data buffer to minimize data dropouts during image transfer
• Reduced amp-glow for superior imaging of faint objects
