I live in the NW area of Phoenix (Peoria). I'm not on the edge of the city but I'm fairly far away from central Phoenix. I have a large backyard and I have my setup in the darkest part of the yard. However, there are still street lamps around that are fairly bright. This is the only place I've used my equipment, I haven't taken it to any remote desert areas...yet. I know star parties are usually held in more remote areas but having no other frame of reference, my question is, how significantly is my viewing being affected by the neighborhood street lights or how much of a difference would it make by taking my equipment to a remote desert area?
