Astrophotography for beginners

ASTROPHOTOGRAPHY for BEGINNERS

(Camera on tripod)

This is how one starts in astrophotography. A camera on a tripod and you're off! Well almost....You will find all you need to begin on this page. Guided astrophotography would be the next step but this demands more equipment and knowledge that I will not cover here.

Example of photos are here: Marjolaine's page

EQUIPMENT:Manual camera SLR 35mm, a cable release, fast film, B setting, lenses with f ratios of 1.4-1.7(if possible), focus at infinity and NOTE everything you do so you may duplicatethe image someday. You can also make your own simple barn door tracker to be able to take longer exposures and you will find the links at the bottom of the page.

note: It is a good idea to shave off a couple seconds from these times to make sure there is no apparent movement of the stars. All the time exposures here should be used as references only. For lenses larger than 180mm, the exposure times would be too short to capture anything worthwhile on the film except perhaps the Moon or other very bright object which demands very short exposures.
