Mars and How to Observe It / Astronomers' Observing Guides (PDF)

Peter Grego is an astronomy writer and editor. A regular watcher of the night skies since 1976, he observes from his home in St. Dennis, Cornwall, UK, with a variety of instruments. His telescopes include a 102 mm refractor, home-made 150 mm and 300 mm Newtonians (telescope mirror-making is another of his interests) and a 445 mm Newtonian, but his most-used instrument is his 200 mm SCT. Grego's primary observing interests are the Moon's topography, Mars and Jupiter. He now likes to use a hand-held computer to make observational drawings.



Grego has directed the Lunar Section of Britain's Society for Popular Astronomy (SPA) since 1984, and since 2006 has been actively involved with the Lunar Section of the British Astronomical Association (BAA). He edits and produces four astronomy publications - Luna (journal of the SPA Lunar Section), The BAA Lunar Section Circulars and Popular Astronomy magazine. He is also layout editor for the Bulletin of the Society for the History of Astronomy and The Antiquarian Astronomer.

Grego's astronomical writings and observations have been featured in many publications since 1983, including the BAS Newsletter, Popular Astronomy, The New Moon, Amateur Astronomy and Earth Sciences, Gnomon, The Lunar Observer, Yokohama Science Center News, and the CD-ROM Window on the Universe. Since 1997 he has written and illustrated the monthly MoonWatch page in UK's Astronomy Now magazine, and he is the observing advisor and columnist for the Sky at Night magazine.

He has given many talks to astronomical societies around the UK and has been featured on a number of radio and television broadcasts.

Grego is the author of numerous astronomy books, including Collision:Earth! (Cassell, 1998), Moon Observer's Guide (Philips/Firefly, 2004), The Moon and How to Observe It (Springer, 2005), Need to Know? Stargazing (Collins, 2005), Need to Know? Universe (Collins, 2006),Solar System Observer's Guide
