With respect, the read noise for those two cameras are very high compared to modern CMOS cameras, meaning he would be forced into longer subs. In his light polluted environment, many short subs from an ultra low read noise camera is going to beat sky glow to a large extent.
And at that RASA focal length, 620mm, smaller pixels have a lot to offer in terms of resolution,imho.
