Which implies the seeing wasn't much good, either.

The dome should be designed to take into account the aerodynamic forces on it in a gale, and whatever you do to mount it must include some means to stop it blowing off as the lifting forces can easily exceed its weight. This should be passive so it doesn't rely on someone putting clamps in place or tying it down before a storm. Same applies to the slit cover. The forces can be very significant BTW. Bear in mind you could be liable if it blows off and damages someone else's property, or a harms a person.

any hidden gotchas ?
the rest is pretty obvious.

The big question is how it will rotate, and manually or electrically. Plenty of info on the intertubes...
