How to Shoot the Night Sky (Introduction to Astrophotography)
The following post on photographing the night sky is by jgomez65 – one of dPS’s forum members. Several people asked me to post a simple tutorial on how I took some night sky pictures. I am not an astrophotographer in any way, shape or form, nor do I have any expensive equipment. I simply read several tutorials, picked a dark spot on the beach and tried to do my best. Anyway, here is how I did it. 1. You need a camera that has manual exposure mode. You will also need a remote control or a shutter release cable in order to minimize shaking the camera when taking the pictures. You will definitely need a tripod 2. The darker the place, the better it is. 3. First, try to use a lens with a large aperture. Next, set your camera at a high ISO. Finally, in order to avoid the star trail (that is avoiding capturing the movement of the stars as the earth rotates) you have to use the RULE of 600 which is very easy: Divide 600 by the focal length of the lens you are using. 4. 5. That’s it. Original Image:

The Royal Astronomical Society of Canada Essay by Michael Silver The Dark-Sky Experience The night lighting of modern urban civilization has completely obliterated the natural glory of a star-filled night for most Canadians. It is now a fact of life that the only time many city or town dwellers ever see the stars is while on vacation in "cottage country". However, even there, local lights at night are now so pervasive that the stars are being beaten back ever farther into the wilderness.
