What is the view (pun) on wall height for a RORO observatory? I have done some research that leads me to the view that is it dependent on your surrounding clearances and what you intend to do - for example, low angle targets look involve looking (or imaging) through at least twice as much atmo as high targets. As I am mainly interested in imaging with my 10" newt, concentrate on higher altitude targets (or wait for them to get there) and thus I am considering that wall height for me maybe more a function of desired headroom (for the scope) with the roof closed.

I am thinking of a wall height of 1.5 metres, with a gable roof to provide the scope clearance and headroom with the roof closed. Is there a common formula for determining this design factor? What are the heights people use?

BTW this observatory is being built under the NSW Exempt Development rules (no Council apprval requird), so max height is limited to 2.5 metres.
