* Light pollution: Cities are notorious for their bright lights, which scatter and obscure the faint light from distant stars and galaxies.
* Atmospheric turbulence: The heat and air currents generated by urban areas create a lot of turbulence in the atmosphere, blurring the images captured by telescopes.
* Clouds and weather: Cities tend to have more cloudy days and less stable weather than remote locations, hindering observation time.
* Air pollution: The exhaust fumes and particulate matter in city air can further obscure celestial objects.
In contrast, ideal locations for optical telescopes are often high-altitude, remote sites with clear skies, minimal light pollution, and stable atmospheric conditions.
