Glendale: The Practical Verdict

Glendale, situated in California, offers a suburban environment with a severely light-polluted sky, characterised by an Extreme Light Pollution tier. As a result, the observing experience is challenging, particularly for deep-sky enthusiasts, as the Milky Way is not visible at all. The predominant issue stems from its proximity to the bright lights of Los Angeles, just 10 km to the south.

From Glendale, observers will find the Moon, planets, bright stars, and double stars to be the most reliable targets. While narrowband imaging can be attempted with care, most forms of deep-sky visual and widefield Milky Way photography should be avoided due to the washed-out conditions.

For those seeking darker pastures, Ventura County lies about 155 km to the south-west. This site offers significant improvements with its Bortle 2 skies, ideal for serious deep-sky observations.
