QHY 183 Mono or Colour.

The QHY183 is a one-inch, 20 Megapixel back-illuminated COLDMOS monochrome or color camera.

The pixel size is 2.4um for high-resolution with modest size telescopes. The camera is capable of producing [email protected] Megapixels. It has a two-stage TEC that cools the sensor to -40C to -45C below ambient. The ADC is 10/12-bit and 8/12-bit output with 1e- read noise! The computer interface is USB 3.0 and exposure times can be set from 50us to approximately 1000 sec.

128MB DDRII Image Buffer

The QHY183 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 QHY183M cameras on the same computer to create an LRGB imaging array.
