Telescope Design and Testing
Portable Newtonian Telescopes. [NEW] Portable Newtonian Telescopes. A massive 694 page book with 472 illustrations and 113 tables that tells you how to design and build a portable Newtonian telescope that performs better, weighs less, and increases your enjoyment of its use.
£ 49.00 (inc VAT) Dispatched within 24 hours.
Telescopes, Eyepieces, Astrographs. Telescopes, Eyepieces, Astrographs. Design, Analysis and Performance of Modern Astronomical Optics is about every optical element between your eye or your imaging sensor and the night sky. This book covers optimized designs found in today’s astronomy market, explores the origins of different systems, analyzes their optical properties and assesses their performance.
£ 46.00 (inc VAT) Dispatched within 24 hours.
Optical Testing. Optical Testing. This practical introduction is written for those working in optics with a practical introduction to optical testing methodologies, instrumentation, and procedures, and assist in the development of their professional careers.
£ 80.00 (inc VAT) Dispatched within 24 hours.
Telescope Optics. Telescope Optics. This book will both arouse your curiosity and answer your questions. Why are there so many different kinds of telescopes? What does each type have to offer? What makes one telescope better than another? Which are best? Why? What are the tradeoffs? As a telescope buyer, you will be better informed; as a telescope maker, you will be able to design custom optics.
£ 29.00 (inc VAT) Dispatched within 24 hours.
The Dobsonian Telescope. The Dobsonian Telescope. This book tells how you can build a state-of-the-art Dobsonian telescope using readily available materials and supplies. Every step of construction is detailed in photographs and diagrams, and the underlying ideas are carefully explained. This is the result of a three-year collaboration between authors David Kriege and Richard Berry, two experienced and well-known telescope makers.
£ 35.00 (inc VAT) Dispatched within 24 hours.

Astrophotography and Photometry
Photoshop Astronomy. Photoshop Astronomy - 2nd editon. Among the myriad computer programs used by astrophotographers, none is as popular or versatile as Adobe Photoshop. However, to take full advantage of the program's capabilities requires vast amounts of time. If a shortcut exists for mastering the tools and techniques needed to properly massage an astrophoto, R. Scott Ireland's book Photoshop Astronomy is it.
£ 46.00 (inc VAT) Dispatched within 24 hours.
Intoduction to Digital Astrophotography. Introduction to Digital Astrophotography - 2nd edition. This book is a 400+ page comprehensive, nuts-and-bolts introduction to digital astro-imaging written by Robert Reeves, an accomplished author and film imager with nearly 50 years of experience who has enthusiastically made the transition to digital imaging. Robert describes how the family digital camera you probably already own can be used to take spectacular pictures of the night sky.
£ 40.00 (inc VAT) Dispatched within 24 hours.
Webcam Astrophotography. Webcam Astrophotography. In the last few years video astrophotography has exploded onto the astronomy scene. It has rapidly evolved from short exposure six-bit black-and-white imagery into long-exposure full-colour 16-bit per channel imagery of such quality that it rivals "conventional" means of astrophotography.
£ 40.00 (inc VAT) Dispatched within 24 hours.
Observing and Photographing the Solar System. Observing and Photographing the Solar System. Covers amateur observation and photography of the planets. Several hundred photographs and line drawings of exceptional quality compliment the clearly written text. Unlike deep-sky observing, meaningful observations can be made in your own backyard.
£ 29.00 (inc VAT) Dispatched within 24 hours.
Astronomical Photometry. Astronomical Photometry. Photometry, the measurement of light flux, is one of the most fundamental and oldest research techniques employed in astronomy. It is also an area where valuable contributions can be made by amateur astronomers using small telescopes. Most people who do photometry have learned the hard way, because how-to books in this field are very few and often incomplete.This book fills the gap for both amateur and professional astronomers who wish to learn the techniques of photoelectric photometry.
£ 35.00 (inc VAT) Dispatched within 24 hours.

Handbooks for Astronomy
Solar Astronomy. Solar Astronomy Handbook. This book is not so much about the Sun, but about the opportunities for amateur astronomers to observe the Sun. This book was conceived and written by a group of German amateur observers. Each section was the responsibility of the amateur who had made that aspect of solar astronomy his specialty. The emphasis was on the practical and covers the kind of solar astronomy within the reach of most amateurs.
£ 35.00 (inc VAT) Dispatched within 24 hours.

Charts and Guides
Messier Marathon Guide. The Year-Round Messier Marathon Field Guide. This "guide" is really much more than the title might suggest.

The whole first third of the book is chock full of practical information on telescopes and observing.
£ 29.00 (inc VAT) Dispatched within 24 hours.
The Arp Atlas of Peculiar Galaxies. The Arp Atlas of Peculiar Galaxies. In 1966, astronomer Halton Arp compiled his Atlas of Peculiar Galaxies, which featured 338 images of some of the strangest looking galaxies and galaxy groups then known to exist. The purpose of the Atlas was to graphically present structural peculiarities in galaxies.

Star Testing. Star Testing Astronomical Telescopes - 2nd edition. Many observers harbour misgivings about their telescope. The manufacturer may have guaranteed accuracy to "one-quarter wavelength" or as "diffraction-limited" but most telescope users have, at best, only a hazy idea of how to personally verifying such claims.
