Amateur astronomy, also called
backyard astronomy, is a
hobby whose participants enjoy watching the night sky
(and the day sky too, for sunspots, eclipses, etc.),
and the plethora of objects found in it, mainly with portable
telescopes and binoculars
?.
Even though scientific research is not their main goal, many amateur astronomers make a contribution to astronomy by monitoring variable
stars,
and discovering transient objects, such as
comets.
Large encounters of amateur astronomers in dark places suitable
for sky viewing are called [star parties]?.
A good place to start exploring the night sky is with the more prominent constellations which serve as markers for many binocular or telescopic objects, and with the Moon and planets.
Some good books for amateur astronomers to start with:
