M42, The Great Orion Nebula, positioned below Orion's belt, is the one of most attractive and photographed objects in the sky. I tried to capture this object into film by using of a telescope at the first time.
Perhaps you can remind this vast nebula of a shining bird with its wings spread out. Actually, M42 occupies only area of this bird's body, and a part of head is named M43 as a detached part of the Orion Nebula. A dark lane separates M43 from M42, although the two are part of the same vast stellar cloud.
You can detect the fascinating four-star system known as The Trapezium with medium sized telescopes (It's invisible in this picture because of over-exposure) in the central region, it's very young stars appear from this gas and dust exquisitely lit by surrounding stars.
