David Levy has held a lifelong passion for comets, and is one of the most successful comet discoverers in history. In this book he describes the observing techniques that have been developed over the years - from visual observations and searching, to photography, through to electronic charge-coupled devices (CCDs).

This book is a step-by-step guide to observing meteors and meteor showers. Any necessary science is explained simply and in clearly understandable terms. This is a perfect introduction to observing meteors, and is ideal for both seasoned and budding astronomers.

Patrick Moore has painstakingly researched Exploring the Night Sky with Binoculars to describe how to use binoculars for astronomical observation. He explains basic astronomy and the selection of binoculars, then discusses the stars, clusters, nebulae and galaxies that await the observer.

This is a high quality CNC machined universal 80mm long dovetail bar by Geoptik. Anodized in their trademark orange for that custom look.

Lightweight and convenient, these stylish compact binoculars feature fully coated optics, quality BK-7 prisms, fold-down eyecups and protective rubber armouring.

This high performance CCD filter transmits only the Hydogen Beta emission line, and therefore is useful for greatly increasing the contrast of objects that glow in the corresponding region of the spectrum, for example the Horsehead, Cocoon and California nebulae.
