Topography & Seeing
Our house is located on the on a Southern facing wall of an escarpment. Often I can use my WO 3.5mm and enjoy magnificent planetary viewing, ATM the views of Saturn are nothing short of breathtaking in the WO 3.5mm.
My question is..... does the fact that our house is situated on a ridge-plateau and that the house and the ridge obscures light from Sydney and the light from Western Sydney explain our good seeing, is it possible to have localised good-seeing?
I had thought seeing was determined by the collum of atmosphere we gaze through rather than localised topography? I can appreciate its a good thing that we observe under a significant Sydney light-shadow though this in no way excludes us from the massive light dome Sydney produces.
Have other Icers noted the effect of light-shadow? Am I simply confusing some good seeing with what I perceive to be a local shadow-effect? Am I subscribing too much to the effect of being in a shadow?
