I've been thinking about it Mick. I need to experiment to work out what size mirror. I'd like to know whether I could get up to my 30x100s using such a system! (Yes, I know the mirror manufacturer says 18x is highest power recommended.) Trying to work out in my mind what the experiment needs to be to determine the size. The other issue would be the dew that would form on the sky-facing mirror. I'm wondering about that as well. So not quite ready to order as yet.
