    *With the improvement of the CMOS technology, the 16bit CMOS camera has been released, like QHY600/268/411/461. For these cameras, even in lowest gain it has beyond the requirement of unit gain (less than 1e/ADU due to sufficient samples) So you can directly set gain0 as start. Please note QHY600/268C/411/461 has extend full well mode. In this mode you still need to find out the unit gain position.

     
    Amp Control Zero Amplifer Glow
    Firmware/FPGA remote Upgrade Fully support via Camera USB port
    Shutter Type Electronic Shutter
    Computer Interface USB3.0
    Built-in Image Buffer 1GByte DDR3 Memory
    Cooling System Two-stage TEC cooler

     

    Less than 1S lower than ambient temperature -30C in continuous mode

    More than 1S continuous mode or lower than ambient temperature -35C in single frame mode

    （Test temperature +20°）
    Optic Window Type AR+AR High Quality Multi-Layer Anti-Reflection Coating
    Anti-Dew Heater Yes
    Humidity Sensor* Yes
    Telescope Interface Support M54 and M48 (with standard adapters )
    Back Focal Length QHY268M: 12.5mm (with CAA)
    If used with the QHY filter wheel, the actual calculated intercept is 12.5mm.The actual BFL (the intercept from the CMOS chip to the top of the camera) is 14.5mm. Since most uses will match CFW with monochrome cams, please take 12.5mm as major reference. Check the mechanical drawing below for details.
    Note 14.5mm rear intercept does not include adapter thread, which must be used with adapters of various sizes through the top 6 screw holes.
