Here's the section on urban astronomy from my post (#22) at https://www.cloudyni...mers/?p=5184287
The vast majority of deep-sky objects visible in amateur telescopes are quite faint and are best seen from a dark location. Stargazing from light-polluted locales can be quite challenging. However, there are a number of DSOs that can be seen by urban observers. The Moon, the bright planets, bright binary stars, bright open and globular clusters, bright nebulae, and bright galaxies are all possible targets.
Light pollution and nebula filters may be useful to some degree on certain nebulae. However, the rising use of broadband LED lighting may render such filters ineffective.

Urban astronomy is also discussed at these sites:
Books on the subject include Urban Astronomy by Denis Berthier and The Urban Astronomer's Guide: A Walking Tour of the Cosmos for City Sky Watchers (Patrick Moore's Practical Astronomy Series) by Rod Mollise.
Lists of binary stars and deep-sky objects that are visible from urban areas can be found at the following URLs:
