I’ve owned an ASI1600 and QHY163M and would still be using the QHY163M if it wasn’t for the gawd awful microlens diffraction. The sensor itself is really good, has some amp glow that easily calibrates out. It could do with a 14-bit ADC as at again 0 it has 12.4 steps of dynamic range available BUT if you run it at again 76 it runs at the full capacity of the ADC. Compare this to the KAF-8300 sensor which has a 16-bit ADC but only about 11 steps of dynamic range.
What I noticed is that on my 8” F/3 it shows up on numerous stars on a mosaic of the SMC which attests to the fact that it’s not only a few bright stars that are an issue. A dozen or so stars around M42 as well.
With my 5” F/5 refractor it ONLY shows up on the bright stars and even then isn’t too distracting.
With my Sigma Art 85mm at F/2.8 it doesn’t show up at all.
So, it depends on what you’re planning on using it with.
As for OSC, I use an ASI094 with both my 8” F/3 and 10” F/10 with great results but I do want to get a mono camera again to do narrowband imaging again.
