Observing Deep Sky Objects
Deep sky objects are simply those objects outside the boundaries of
our solar system. They include star clusters, planetary nebulae,
diffuse nebulae, double stars, and other galaxies outside our own
Milky Way. Because your spotting scope is not set up for serious
astronomical observing, you will need to know where to look in the
sky for these objects. The Celestron Sky Maps (#93722) will help you
locate the brightest deep sky objects.
Once you start observing deep sky objects, there are a few things to
remember. First, most deep sky objects have a large angular size.
Therefore, low to moderate power is all you need to see them. Second,
visually they are too faint to reveal any color that is common to
photographs. Instead, they have a black and white appearance. And
lastly, because of their low surface brightness, they should be ob¬
served from a dark sky location. Light pollution around large urban
areas washes out most nebulae making them difficult, if not impos¬
sible, to see.
