I'm back in the southern hemisphere and well north of the southern jet stream. The seeing should be good except that October tends to bring a lot of rain... maybe an expedition to the desert is warranted.
On scopes - I've just started a 10" f /9 that will be built roughly along Ed Turco's Definitive Newtonian. The trick will be finding local glass for a 10" window. (Failing this, I'll use a spider until I can get glass.) Since it's intended for shallow space observing, I'll build in an integral Barlow and achieve something like 3500-4500 mm effective focal length. My 16 mm ZAO II's seem to be perfectly suited.
The problem with a scope this extreme is the distance between its mirror-end and the eyepiece - probably close to 86". There's no way I want to stand & make critical observations, so I'm thinking about digging a pit for half the scope to hide in.
However I finish it, I'll be interested to see how it shapes up against my TOA150 (this is refractors after all!).
Edit... how could I forget, I have the keys for the 26" refractor up at the observatory.
