M81 & M82 from the Starizona parking lot

This unguided image was taken with a Celestron 14" SCT from the Starizona parking lot, about 50 feet from a major 6-lane road.  We often have a hard time convincing people that it is possible to image from light polluted skies.  "You're in Arizona," they say.  So we explain that we're in a parking lot new to a road.  "Yes, but you're in Arizona," they reply.  Okay, here's a picture of our parking lot while the above picture was being taken:

Not exactly the dark skies Arizona is famous for.
