Bøger af Stephen James O'Meara

The Caldwell Catalogue, compiled by the late Sir Patrick Moore (1923-2012), has delighted amateur astronomers worldwide since its publication in 1995. Twenty years on, Stephen James O'Meara revisits his guide to these 109 deep-sky delights, breathing new life into them and the 20 additional observing targets included as an appendix. This second edition retains O'Meara's detailed visual descriptions and sketches, accompanied by stunning new images taken by amateur photographer Mario Motta and observations by Magda Streicher. The astrophysical descriptions have been updated to account for the many advances in our understanding of the objects, not least due to an armada of space-borne observatories and the new technologies used in large ground-based telescopes. Ideal for observers who have completed the Messier objects and are looking for their next challenge, Deep-Sky Companions: The Caldwell Objects is a fitting tribute from a renowned visual observer to one of astronomy's most famous personalities.

The bright galaxies, star clusters, and nebulae catalogued in the late 1700s by the famous comet hunter Charles Messier are still the most widely observed celestial wonders in the sky. The second edition of Stephen James O'Meara's acclaimed observing guide to the Messier Objects features improved star charts for helping you find the objects, a much more robust telling of the history behind their discovery - including a glimpse into Messier's fascinating life - and updated astrophysical facts to put it all into context. These additions, along with new photos taken with the most advanced amateur telescopes, bring O'Meara's first edition more than a decade into the twenty-first century. Expand your universe and test your viewing skills with this truly modern Messier guide. It is a must for all budding night watchers.

The vast night sky holds a special attraction for young readers, and Stargazing with Jack Horkheimer: Cosmic Comics for the Sky Watcher captures that sense of wonder in words and pictures. Jack, whose monthly cartoon "Stargazing with Jack Horkheimer,” has been a popular feature in Odyssey Magazine for many years, appears in animated form. As his human counterpart does in real life at the Miami Space Transit Planetarium, this cartoon Jack guides youngsters into space, helping them to explore the amazing lore and science of the moon, the sun, the planets and constellations, and other objects visible in the night sky. The book also introduces the basic concepts of stargazing and mind-boggling facts - all presented from the viewpoint of Jack and his quirky cast of cartoon characters. Individual chapters cover "The Bright Stars and the Patterns They Make,” "Seasonal Star Watching,” and seasonal sky changes. Included are more than 50 cosmic comics, seasonal star-watching activities, star charts, tips for the best sky-watching, and an astronomy glossary and index.

This useful guide for amateur astronomers takes readers on a celestial journey to many of the most prominent stars and constellations visible from mid-northern latitudes. A great first-time reference, this book will help beginning stargazers become familiar with the stars and constellations visible from their backyards through inexpensive, handheld binoculars.
