[Atmob-discuss] observatory dome versus roll-off - looking foradvice

[George Roberts]

You guys are great.  I got great advice on the roll-off versus dome 
issues.  Not just from Mario and Steve but some off-the-list responses 
also.  Basically for educational purposes (larger groups), roll-off is 
better.

We are planning to have low walls (about 5 feet probably).  Any advice 
about designing and building roll-offs would be great.  e.g. I'm 
currently thinking of having the entrance door extend up into the gable 
so there is no possibility of the roof ever hitting the scope.
