Astrophotography for the Amateur

Description

While in this age of digital imaging the equipment in this book is dated. However the general information on the basic principals of astrophotography are still in many cases very much the same.

Astrophotography for the Amateur tells how to take pictures of the stars, galaxies, planets the moon, the sun comets, meteors, and eclipses, using equipment and materials readily available to the hobbyist during the end of the twenty century and film cameras of today.

The first section “Getting Started” presupposes little knowledge of photography or astronomy and concentrates on what can be done with minimal equipment. An ordinary 35 mm camera on a tripod aimed at the sky on a starry night will photograph more stars than the unaided eye can see and will bring out a variety of colors. Add a long telephoto lens, a pair of binoculars or a small telescope and you have all that is needed to photograph an eclipse or show the main features of the moon.

The two subsequent sections, Advanced Techniques and Equipment and Materials cover the use of cameras in conjunction with telescopes and constitute a through handbook, including technical information on optical systems, film characteristics, and processing techniques. Throughout the emphasis is on current pratice, which – because of recent developments such as gas-hyper-sensitization, solid state electronics and low cost mass production of compact, portable telescopes – is quite different then things were done a few years ago.

Note: It should be pointed out the book contains dated materials and does not cover digital cameras, digital chips or methods of computerized control of equipment or telescopes. It is excellent reference material however if you would wish to attempt film photography for astronomical purposes.
