An essential item of equipment for beginners and experienced observers, Philip's Planisphere enables the user to locate stars, constellations and planets, and work out sunrise and sunset times for every day of the year. Simply turn the oval panel to the required date and time to reveal the whole sky visible from your location.This brand new edition of the Philip's Southern Planisphere is larger, clearer and easier to use, while remaining lightweight and portable. The new map, drawn by renowned celestial cartographer Wil Tirion, shows stars down to magnitude 4 (stars visible with the naked eye), as well as many deep-sky objects. On the back of the planisphere are tables giving the positions of the four visible planets - Venus, Mars, Jupiter and Saturn - for every month until 2012.The Southern 35 Planisphere is suitable for use in Australia, New Zealand, southern Africa and Southern America.the WALLETNew for this edition is the full-colour wallet. Divided into two main sections - 'Using the planisphere' and 'Exploring the skies' - it provides indispensable information for the first time observer.'Using the planisphere' gives illustrated step-by-step instructions on how to set the planisphere to the right date and time, how to locate the planets and how to work out the time of sunrise or sunset. It explains the details seen on the map, such as the magnitudes of stars, the ecliptic (path of the Sun) and the celestial coordinates.'Exploring the skies' is an excellent beginner's guide to stargazing. It introduces the novice astronomer to the principal celestial objects visible at different times of the year. Major constellations are used as signposts to navigate the night sky, locating hard-to-find stars and some fascinating deep-sky objects.Main map scale:
Invaluable for both beginners and advanced observers, Philip's Planisphere (Latitude 32 North) is an essential travel accessory for astronomy enthusiasts visiting the USA, North Africa, the Middle East or Southern Japan, for example. To use this practical hour-by-hour tracker of the stars and constellations, you simply turn the oval panel to the required date and time to reveal the whole sky visible from your location.The map, by the well-known celestial cartographer Wil Tirion, shows stars down to magnitude 5, plus several deep-sky objects, such as the Pleiades, the Andromeda Galaxy (M31) and the Orion Nebula (M42). Because the planets move round the Sun, their positions in the sky are constantly changing and they cannot be marked permanently on the map; however, the back of the planisphere has tables giving the positions of Venus, Mars, Jupiter and Saturn for every month until 2020.The planisphere is supplied in a full-colour wallet that contains illustrated step-by-step instructions for how to use the planisphere, how to locate planets, and how to work out the time of sunrise or sunset for any day of the year. It explains all the details that can be seen on the map - the magnitudes of stars, the ecliptic and the celestial coordinates. In addition, the section 'Exploring the skies, season by season' introduces the novice astronomer to the principal celestial objects visible at different times of the year. Major constellations are used as signposts to navigate the night sky, locating hard-to-find stars and some fascinating deep-sky objects. The movement of the stars is also explained.
Supporting these articles are shorter entries on planetary features and satellites, asteroids, observational techniques, comets, satellite launchers, meteors, and subjects as diverse as software for astronomy and the structure of meteorites."--BOOK JACKET.
This volume collects 22 papers presented at the 4th International Symposium of the ICA Commission on the History of Cartography, held at Eotvos Lorand University, Budapest, Hungary, on 28-29 June 2012. The overall conference theme is 'Exploration - Discovery - Cartography', but preference has been given to papers dealing with cartography in the 19th and 20th centuries. The papers are classified according to regional sub-themes, i.e. papers on the Americas, papers on Africa, etc.
Many encyclopedia entries (from aberration to ZZ Ceti star) authenticated by a team of respected academics. Colour illustrations, photographs, artworks, and tables. Star Maps created by Wil Tirion.
So begins Sabine Baring-Gould's account of his journey on horseback around Iceland in 1862. Aged twenty-eight, the young writer and teacher was fascinated by the tradition of the Icelandic sagas, and this was the catalyst for his adventure and the book that emerged from it. His voyage took him from the then tiny settlement of Reykjavik through remote and hostile terrain, passing through the empty expanse of Iceland's countryside. He observed mountains and glaciers, volcanoes and geysers, wondering at the wild beauty of the landscape. He also recorded the rich flora and fauna that he saw-and, to his chagrin, that his companions shot.

This book enables anyone with suitable instruments to undertake an examination of nebulae and see or photograph them in detail. Nebulae, ethereal clouds of gas and dust, are among the most beautiful objects to view in the night sky. These star-forming regions are a common target for observers and photographers. Griffiths describes many of the brightest and best nebulae and includes some challenges for the more experienced observer. Readers learn the many interesting astrophysical properties of these clouds, which are an important subject of study in astronomy and astrobiology. Non-mathematical in approach, the text is easily accessible to anyone with an interest in the subject. A special feature is the inclusion of an observational guide to 70 objects personally observed or imaged by the author. The guide also includes photographs of each object for ease of identification along with their celestial coordinates, magnitudes and other pertinent information. Observing Nebulae provides a ready resource to allow anyone with a little experience in astronomy, whether professional or amateur, to locate, identify and record the nebulae in our home galaxy. The author enables the observer to use a telescope and filters to the best advantage to see these celestial wonders, or to couple filters to a CCD camera or digital SLR camera in order to take quality images of celestial objects. By using these techniques it is even possible to make a valid contribution to professional investigations. And the views are unbeatable.
Victorian Telescope Makers is the story of a highly specialized & unusual business enterprise, that of telescope manufacture. Makers of some of the largest & best known telescopes of the Victorian era, the Grubbs of Dublin placed themselves at the forefront of optical & mechanical engineering in a world where continual innovation & improvement were the keys to success. For 95 years Thomas & Howard Grubb, father & son, supplied astronomical instruments to the world. Through extensive use of their original letters & documents Ian Glass has allowed the Grubbs to speak for themselves. The story recounted is of the development of a small leading-edge technology firm from its beginnings in 1830 as a billiard table manufactory to its eventual position as one of the major telescope makers of the Victorian era. The founder of the firm, Thomas Grubb, was an innovator in the field of telescope making & optical design. One of his earliest instruments was, for several years, the largest telescope in the world. Howard, the son, formalized the business, built a new factory & capitalized on the rapid growth of astrophysics. He in turn obtained the contract for the world's largest refractor, the 27 inch centrepiece of the Royal & Imperial Observatory in Vienna. Together, the story of Thomas & Howard Grubb provides an unique insight into a period of rapid growth & innovation in Victorian science. This book will prove fascinating to all those interested in the history of telescope manufacture & of astronomy as well as to students of the Irish past.
