My first imaging scope was a reflector – a Skywatcher ED80 – and, although I loved it and learned to image well with it, […]

They are even more important, in my opinion, when shooting multiple shorter exposure subs on a CMOS sensor. Having quality dark files is therefore something we all need – the problem is, they need to be consistent with […]
