Firtsly, allow me to briefly introduce myself because I am not a big forum user. I am Lóránd Fényes Hungarian astrophotographer, member of the Hungarian amateur astrophotographer community. I have been cooperating with QHYCCD as (beta) product tester since 2014. I tested QHY8300 and 168C before and this february was asked to test the new 183M. Sadly in Hungary this spring period was creazy, our country experienced a bigger weather anomaly. Usually in March is our spring time but now we had -20 celsius degree and more than 40-70 cm snow for weeks. So I had a delay but finally have just finished the first lights with 183M. I know that it is a little late but maybe could be useful.
The camera is good, the noise level is more than great. It has an observable amp glow but we can handle it woth darks.
