Seriously? Hard to discern anyting in all the glare :-)

Dig a little futher down in that site and you will see the answer - LPS lamps. Now, all you need is a narrow band filter (yellow) over all your windows and it will be pitch black (almost). Get some custom made glasses with those filters and you are all set. Though the dome is a great idea for other reasons also...

>Any hobby is a black hole - you are so correct!

Indeed. Well, beats buying a SUV.
