Weight (net)
 (The weight does not include the M54/0.75mm center/tilt adjust ring)
Scientific Professional Version : 915g
Early Bird Version : 915g
Amateur Photograhic Version: TBD
Reference Price (TAX not included)
Early Brid Version Price:            USD5000 *
Scientific Professional Version:  USD8000
Amateur  Photographic Version: TBD

* The Early bird version is using the same hardware and structure of the Scientific Professional Version.In future it can be upgrade to the scientific Professional version by patching the color different.  The Early Bird price is USD5000 for Monochrome and color version.  The QHY600 Early Bird Price is effective from Aug,20, 2019 and will end in approximately about 2-3 months.  when the Photographic model is released, or when the Early Bird inventory is exhausted, whichever occurs first..  The early bird includes a special offer for an 10% discount for ordering QHYCFW3XL/QHYCFW3L filter wheel together. 




Readout Mode is a new function for new QHY Cameras. Different Readout Mode have different driver timing etc and causes the different performance results. Each readout mode has its advantage and disadvantages. QHY600 currently has three readout modes. And in future QHYCCD may add more modes. The Readout mode currently supported by QHY ASCOM Camera Driver and SharpCAP software and the N.I.N.A software. You can find the list box in the software.

QHY600 Performance Curves in Readout Mode #0 (Photographic Mode).  In this mode . Between Gain25 and Gain26, There is a readout noise drop position. We recommand to use the Gain26 for beginning. In Gain=26, the fullwell is 27ke and readout noise is 2.7e. For every long exposure. You can use lower gain to get better fullwell. 










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 is using LGC and Gain55-100 is using HGC.




 








QHY600 Performance Curves in Readout Mode #2 (Ultra High Full Well Mode).  












The QHY600 QE is not the absolutely QE. It is the uniformed relativity QE .  QHYCCD did some test of absolutely QE test for QHY600. It can be used for just a reference.  This article can be found in https://www.qhyccd.com/index.php?m=content&c=index&a=show&catid=23&id=261
