The loss of dark skies is so painful, astronomers coined a new term for it (www.space.com)

Given the harmful effects of light pollution, a pair of astronomers has coined a new term to help focus efforts to combat it. Their term, as reported in a brief paper in the preprint database arXiv and a letter to the journal Science, is "noctalgia." In general, it means "sky grief," and it captures the collective pain we are experiencing as we continue to lose access to the night sky.

Sounds like you might have some binoculars. 7x35 or 8x42 or 10x50 binos are great for scanning the night sky. Outer lens diameter divided by zoom = inner lens diameter which you want to be 5mm or greater. 35/7=5 and 42/8=5.2 etc. Some larger "deep sky objects" such as Andromeda galaxy, Lagoon Nebula, Orion Nebula, and Hercules cluster pop right out in my nikon ae 10x50s. Again, they're just smudges, but they're such stationary smudges you'll swear the sky is a painted dome.
