Astrophotography presents many unique challenges and rewards. A few astronomical objects and events are observable during the day or can be photographed with wide angle lenses, but most have a small angular size and are so dim that they are visible only at night. When photographing such dim and distant subjects, good high resolution optics, fast film, a long focal length, and a large aperture are advantageous. This usually implies the use of a large telescope, but there are ways to get relatively good images with a small telescope. Selection of a good observation site is also important, because city lights, clouds, or fog can wash out or obscure one’s view of the night sky.
