Hi, I have a permanent setup in my small backyard, with an ED120 on a pegasus pier concreted in. No dome, just a weatherproof cover. We're thinking about getting a new r/c ducted aircon, and the outdoor unit might have to go in the backyard. Have others experienced air distortion due to an a/c outdoor unit? The unit will probably be about 6m away from the telescope. We live in Canberra so the aircon will probably be running regularly on winter nights to keep the non-astronomers warm inside.
