I think I just need to setup a permanent observatory at a dark site, live near by, be financially independent and not need to work and have easy access to high speed internet and other mod-cons. Everything else is a compromise.
Some form of tent might be the way to go for the portable aspect. I can do something else for the backyard.
It's not completely clear from the pics on the Sirius Optics site for the tent - is it just the one opening in the front?
