The most detailed guide to observing the deep sky in one volume, now available in paperback.

Atlas over de vigtigste galakser og nebuloser, som kan ses i teleskop af amatørastronomer.

The most comprehensive, detailed, and beautiful account of the Messier objects available, for amateur astronomers of all abilities.

An introduction and reference guide to finding and studying 690 of the sky's deep-sky objects using a backyard telescope.

Deep-sky observing is easily the most popular field for amateur astronomers. The big problem faced by non-professional observers is what to look at - what is visible at a particular time of year. The Deep-Sky Observers Year is a month-by-month guide to the best objects to view. Objects are given a "star rating" according to how difficult they are to observe or image with a particular size of telescope. The book includes many images produced by amateur astronomers, as well as photographs from NASA, ESA, and ESO. There is background information about the objects, along with lots of useful tips, hints, and resources.

Guide to Observing Deep-Sky Objects is an invaluable reference for all amateur astronomers. The book contains, for each constellation, (1) a star chart showing the Bayer labels, (2) a table for many of the stars in the constellation, along with their positions and magnitudes, and (3) a table of the major deep-sky objects in the constellation, with relevant observational data. Facing pages provide unique year-long graphs that show when the constellation is visible in the sky, which allows the user to quickly determine whether a given constellation can be seen, and when the best time to see it will be.

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.

Faint Objects and How to Observe Them is for visual observers who are equipped with a 10-inch or larger astronomical telescope and who want to "go deep" with their observing. It provides a guide to some of the most distant, dim, and rarely observed objects in the sky, supported by background information on surveys and objects lists - some familiar, such as Caldwell, and some not so familiar. This book not only provides a wealth of experience compiled from several sources, but it also gives an historical background to surveys whose names may or may not be familiar to most amateur astronomers. Finally, it includes a listing of the many galaxy clusters out there, from "nearby" ones such as Stefan's Quintet to some of the most distant groups observable through the largest telescopes.
