Astrophotography on the Go - Using Short Exposures with Light Mounts
Authors: Ashley, Joseph
- Explains how to carry out prime focus photography of deep space objects with a DSLR and an altazimuth mount
- Guides amateur astronomers to the best and most affordable equipment for their purposes
- Advises how to conduct ‘portable astrophotography’ when traveling
No longer are heavy, sturdy, expensive mounts and tripods required to photograph deep space. With today's advances in technology, all that is required is an entry-DSLR and an entry level GoTo telescope. Here is all of the information needed to start photographing the night sky without buying expensive tracking mounts. By using multiple short exposures and combining them with mostly ‘freeware’ computer programs, the effect of image rotation can be minimised to a point where it is undetectable in normal astrophotography, even for a deep-sky object such as a galaxy or nebula. All the processes, techniques, and equipment needed to use inexpensive, lightweight altazimuth and equatorial mounts and very short exposures photography to image deep space objects are explained, step-by-step, in full detail, supported by clear, easy to understand graphics and photographs.
Currently available lightweight mounts and tripods are identified and examined from an economic versus capability perspective to help users determine what camera, telescope, and mount is the best fit for them. A similar analysis is presented for entry-level telescopes and mounts sold as bundled packages by the telescope manufacturers. This book lifts the veil of mystery from the creation of deep space photographs and makes astrophotography affordable and accessible to most amateur astronomers.
About the authors
An American by birth, Joe Ashley currently lives in Greece. His career in the U. S. Navy included the recovery of astronauts Conrad and Cooper and their Gemini V spaceship from the sea; from there he began an engineering and research career (probably only possible at that time in history) involving submarine noise, chemical warfare defence, and energy conservation. Along the way, he obtained a doctorate in Public Administration. Now retired, he completed his career as the Program Manager for the U. S. Department of the Navy and Marine Corps Energy Conservation Program. Recently, Ashley has participated in on-line astronomy forums, primarily the Stargazers Lounge and The Astronomy Forum. In late 2009 he became a moderator on The Astronomy Forum, the world’s largest (based upon membership). Parallel with that, he pitched into what he calls “the dark side of astronomy” – astrophotography – concentrating on getting the best possible images from simple lightweight equipment.

as someone from a purely “visual” background keen to have a go at astrophotography this book seemed like a godsend and was reasonably well reviewed. It contains a wealth of useful information about how to get the best from different mount types, packing for travel and the science behind camera sensors etc. But, for me, it seems to go way way too deep for its intended audience on things like how camera sensors and signal to noise ratios impact an image; yet seems to almost completely omit other areas like how to get the best from polar alignment, how to take good darks or flats or bias frames etc. And there’s a whole massive section at the rear with lists of telescopes and their native apertures that is already mostly out of date and I can’t see how it would be much use to anyone. It feels a little like it’s a combination of several unconnected chapters that have been squashed together making the whole thing feel a bit inconsistent. Still a worthwhile read though - lots of great info, just takes a while to find it!,
