Yes, I use the Unihedron (unihedron.com) regularly from my back garden observatory. They are an excellent way of assessing observing sites but the night to night variation from a single site can obviously vary significantly depending on conditions. If you are a deep sky observer searching for faint objetcs they are a good way of checking how likely you will in seeing your target.
