As stated below, buy one and test it, and publish the photos here. If your looking for a reason to not buy a 1600, so be it, don't buy it.
Potential 183 buyers should read Jon Rista's excellent review which he conducted for ZWO and published on CN, here:
https://www.cloudynights.com/topic/5...d-asi-qhy-etc/
And note Jon's final conclusion, on his opening post: "... don't expect the IMX183 to be an "ASI1600 killer" in any way."
It is a long thread but well worth looking through all of it. Jon goes into amazing testing detail. Note Jon owns a 1600 and has tested it extensively.
Note that within that CN thread, user "rockstarbill" states the 183 sensor surface is "AR coated", and this is the only reference in the entire thread. There is no explanation for how the sensor surface is AR coated.
In theory, a back illuminated sensor should produce less reflectivity due to pixel wiring being relocated to the back, and the QHY183 ads make mention of this.
