“Every inch of its king-sized pages is packed with artistry, information, lucid diagrams, and clever explanations” —J. U. Gunter in Tonight's Asteroids

“So valuable that many users keep their copies for permanent reference” —George Lovi in Sky & Telescope

“Each year's book becomes more superb—just when you think it can't get any better!” —A reader in Florida

“Thank goodness for Guy Ottewell. If he didn't exist, I would have to invent him... [The book is] of surpassing originality [and is] more than a calendar; it is a compendium of all things astronomical that will happen during the year, described with a graphic flair that is the author's particular genius. The calendar is useful for neophytes, but it also evokes the appreciation of experienced astronomers. It arrives every year in December and, during early winter evenings, I curl up with it and plan my coming year of stargazing.” —Chet Raymo in The Boston Globe

“It's hard to find one word to describe Ottewell's Calendar: marvelous, educational, illuminating, and classic just seem to scratch the surface. Beginning and veteran observers alike love this book. I consider it a must-have even for armchair astronomers. If you don't have a copy, buy one today... The diagrams showing the motions of the planets and comets are alone worth the price of this book.” —Dave Bruning in Astronomy magazine

“This is my husband's favorite Christmas gift. I could buy him the moon and he would like this book better.” —Lynda Detray, Troy, New Hampshire

“Kudos for getting all the Comet ISON material in!!!!!! Even SkyTools doesn't have all the new comets in yet. And RASC went to publication too early to include it.” —Jane Jones, Cassini program, NASA

“I enjoy the Astronomical Calendar so much that every year I also treat myself around Christmas to buying one of the earlier issues. I collected 1981, 1983, and 1985-1989 and this year found 1978 and 1984 on the used market. I found a copy of 1980 but the owner priced it at over $100...” —Eric David, Virginia
