My 10" portable dobsonian by Sumerian Optics. I think this scope is the ideal compromise between aperture en portability. And it's virtually invisible when packed up which makes the missus very happy :D
Here you see it in it's natural environment somewhere in between Hamburg and Berlin, my favorite observing site.

It's a 9.5kg telescope and it packs up so small you can actually take it with you in the plane as hand luggage.
