In a previous story I covered some galaxies that you can see reliably even under washed-out skies. Unfortunately some relatively bright galaxies that amateurs everywhere know and love are particularly susceptible to the effects of even modest light pollution. If you live in urban or suburban areas, you can spend hours looking for these without success. To save you this frustration, I’ve prepared a list of famous galaxies that are very hard to see in washed-out skies. You can treat this as a list of galaxies to avoid, or if you prefer, consider it a challenge list for observing under washed-out skies....
