Galaxies present a unique challenge to town dwellers. Amateur astronomers can't use narrowband filters to shut out light pollution or use ordinary techniques as they would in dark, open fields. As one can imagine, this discrepancy with light means not everyone who looks up at the night sky is capable of seeing all it has to offer. What a shame!
Author Jane Clark, however, has spent two years going down blind alleys trying to get a technique to work to combat the amateur astronomer's biggest enemy, light pollution. In this book, you will discover the fascinating variety of galaxies: spirals, ellipticals and irregular galaxies, often sculpted by gravity as they encounter one another in the vastness of space. You will also learn how to image them, as well!
While the most decent images pick up background galaxies 10-20x as far, each containing billions of stars, that's just the local universe! This book will help you observe for yourself right in your own backyard, allowing you to get a sense of the sheer vastness of the universe.
