My roll-off roof

I built my backyard roll-off roof observatory last summer, it is 12' by 11', the pier is towards one side so there is plenty of room to spread out.I've been in a 6' and a 8' dome and it seemed very cramped, even with only two people observing.

Here is the interior, to give an idea of the room to spread out, I could set up a cot and sleep in there.(some nights I do!!)
