Abstract: Amateur observational astronomy is the unlimited hobby of learning about the universe and observing as the base of astronomy.It can be divided five major types of amateur observing as observing with your unaided eyes [naked eye] without optical aids, Observing with binoculars, observing with telescopes , observing with cameras that use film and electronic technologies & Astronomy spectroscopy, Each kind of observing is based on learning how to use different types of observing equipment. Sky is a natural laboratory for every amateur astronomers in the world,But The sky that our students can observe is not impressive. In the 21st century images are of outstanding importance, the appearance of the sky is awful. From many cities it is not possible to look at the sky, but when we find a space between the buildings to see the sky, the light pollution reduces the full numbers of visible stars to a few.How ever if could going through the barriers of observation astronomy, its become as part of our life. Then we can look at the sky to rediscover the stories of our ancestors & Promote positive feelings towards astronomy and towards science in general.Thus amateur astronomers can help people to discover and taste the adventure of a new knowledge by means of simple observations using the naked eye, binoculars, amateur telescopes or public observatories & Impress upon humanity the beauty of natural phenomena also you can be step forward for keep something so wonderful.
