Had a look at the Bintel calculator, it gives the 1600 "Slight oversampling" both with and without the 0.63 reducer, and the same for my ASI294. I am awaiting arrival of an SCT thread UV-IR filter to see if it has as dramatic an effect on reflections on the SCT as on the ED72.

The ED72 would also be another prospect though it will probably be in line for an upgrade later, I am sure mono would uncover it's weakness in the blue end of the spectrum. The 1600 would be less undersampled than my 294 on that scope though.


Edit, gain wise I run the 294 at unity, for deep sky stuff nothing else really makes sense to me as one way will increase the apparent dynamic range but at the cost of non linearity (If one converted photon equals less than one electron it can not be linear) and the other way crunches dynamic range AND makes it non linear aside from gains that are whole multiples of 1. I used to run 0 gain but once I worked that one out I went to unity and have stayed there ever since.
