The QHY600 uses the latest SONY IMX455 back-illuminated sensor, a full frame (35mm format) sensor with 3.76um pixels and native 16-bit A/D. This sensor is available in both monochrome and color versions. The sensor size is 36mm x 24mm. With the round body design, the QHY600 is an ideal camera to match the image circle of the new generaltion of RASA telescopes.

|
| Model | QHY600U3 (Photographic Version) |
| Image Sensor | SONY Full Frame BSI CMOS Sensor IMX455ALK-K (Industry Grade) This sensor is available in both -C (consumer grade) and -K (industry grade). General speaking the -K version has longer lifetime than the -C version. Currently ,both the monochrome QHY600 Photographic version and monochrome QHY600 Professional version use the -K version of the sensor. |
