In the Cloudy Nights thread on this subject, many people mention AR glass (specifically "Protect window:AR window") included in the various ZWO camera specs, and yes the top camera housing glass window is AR. The issue concerning reflection is related to the glass used over the sensor surface, which is bonded on during the sensor production process - it is not AR. Just about every reference concerns Alnitak.
It is possible the 183 is not affected but it would be entirely related to the chip surface characteristics and the sensor area cover glass. You should buy one and test it on the Flame Nebula and the Horsehead, with Alnitak in frame.
