A/D
16-bit (0-65535 levels) at 1X1 binning
 
18-bit at 2X2, 19-bit at 3X3, 20-bit at 4X4 software binning

*QHY600 uses the software digital binning for 2*2binning. With digital sum, 2*2binning will be four 16-bit summed then it is 18-bit.

About the early-bird version:
It has the same features as the Amateur Photographic version but with the hardware and structure as the Scientific Professional Version.  The Professional features can be enabled in a future upgrade for the difference in price.  When released, the Amateur Photographic version of the camera will have only the hardware for the features of the Photographic model and will not be upgradeable.  The Early Bird price is USD5000 for Monochrome and color version.  The QHY600 Early Bird Price is effective from August 20, 2019, and will end when the Photographic model is released or when the Early Bird inventory is exhausted, whichever occurs first..  The early bird version also includes a special offer for a 10% discount on the QHYCFW3XL/QHYCFW3L filter wheel when ordered with the camera.

Multiple Readout Modes is a new function for newer QHY Cameras.  Different readout modes have different driver timing, etc., and result in different performance.  Each readout mode has its advantage and disadvantages.  The QHY600 currently has three readout modes.  In the future QHYCCD may add more modes. These readout modes are currently supported in the QHY ASCOM Camera Driver, SharpCAP software and the N.I.N.A software. You can find the readout list box in the software.

QHY600 Performance Curves in Readout Mode #0 (Photographic Mode).  In this mode there is a drop in the noise between Gain 25 and Gain 26.  We recommend setting the Gain to 26 to begin.  At this setting the full well is 27ke- and readout noise is 2.7e-.  For every long exposures you can lower the gain from this point to increase the full well capacity. 


 
QHY600 Performance Curves in Readout Mode #1 (High Gain Mode).  Please note there is a HGC/LGC switch point at gain55 to gain56. Gain0-55 uses LGC and Gain55-100 uses HGC.









 
 

 

QHY600 linear test results show good linearity up to 73000e-.  This is in readout modes # 0 and # 2. Gain = 0. In the linear fit graph we deleted the data above 73000e- and got R ^ 2 = 0.9998.\
At very short exposure times below 20ms the value is quite small and may be flicker induced by the tablet.
