4-14-2017 - The new OITHv6 is due today from the printer. This version has been nearly 3 years in the updating process; nearly every page and map has been tweaked, modified or added to and newly found objects added.
6th edition features: 500+ updates including 1.2020 RA/Dec address; many previously unlisted objects; seven pages on the Moon; and lots more! Lowell Observatory stocked their bookstore with 30 copies.
OITHv6 is the newest pocket-size astronomy deep-sky fieldbook for viewing the night sky from the northern hemisphere. Includes descriptions and mapped locations of 739 celestial objects of all types to magnitude 10, all with 1.2020 RA/Dec addresses.
Aside from copious details on deep-sky objects, 7 pages are included on viewing the Moon so you can follow what's visible as Earth's "night light" goes through its phases during the month. (scroll to the bottom of THIS PAGE to see a sample spread)
All known objects to magnitude 10 or brighter, those visible with a 6-inch reflector or larger, are detailed and mapped. 191 entries of mag 7 and brighter ("city objects") are specially highlighted for use with average binoculars. Data has been assembled from 38 astronomical catalogs, including 259 other-than-Messier or NGC objects. Generous space is provided in the back for personal observation sketching and notes.
OITH is designed for both the casual viewer and experienced deep-sky hunter. By having useful information at your fingertips, in a format that's easy to use at home or at a dark site, you spend less time searching and more time viewing.
Have you wondered what you can actually see in the night sky? OITHv6 will help you find more objects from city sites or dark sites, with telescopes or binoculars.
It's an interactive reference book which brings together just the facts – and then some – to be a complete, useful and entertaining viewing companion. While OITH is not a photo book, the images included are what you can expect to see in your eyepiece.
OITH provides many answers to: "What ALL can I see and where is it?" by providing only those objects which are potentially viewable from the Northern Hemisphere, formatted to simplify finding these visual treats with 74 detailed constellation and seasonal maps. Featured are modern celestial locations (1.2020 addresses), available descriptions, extensive cross-referencing, common names list and historic observational comments from T.W.Webb. The book's compact size also makes it ideal for camping and hiking.
OITHv6 by the Numbers:
132 pages, lay-flat spiral-binding, soft cover, digest size: 5.5" x 8.5"
Feedback and reader opinions are necessary for improving this effort. I now enjoy a great relationship with some amazing people who are properly thanked on the front acknowledgement page. The reviewers' page has many wonderful comments from astronomers of all experience levels, beginner to professional.
I hope you like this book as much as they do.
About the Author
I enjoy the quiet of the country and my preference for hobbies springs from that attraction. Astronomy has not only been a particular focus of study culminating with this book, it's best done far from city lights and Chicago has a lot of them. My other interest, hang gliding, dates from 1977 and is also best done in places far from the city.
My fascination with astronomy had several false starts but, like an old Harley-Davidson in need of a tune-up, it needed one more kick to get it going. My father pointed out a very red Mars when I was about 8 or 9, then I witnessed the 1966 Leonids, spent a year near the equator and saw our neighbor galaxies. None of that worked. The final kick start was seeing Jupiter through a friend's 8" reflector in '94. Wow! I had to learn more.
What started out as simply "what can I see" with my new (very old) 6-inch reflector lead to a quest to find every object of magnitude 10 or brighter. The mag-10 limit was originally set as it's the practical limit of the 6" scope in average skies. This turned out to be a fair limiting number as more and more objects were uncovered. The search itself involved dozens of libraries, 100's of books, magazines and literally thousands of websites. Each time new data was collected, the humble list began to increase, eventually growing beyond my wildest dreams. That basic first list took on a life of its own and, of course, became the book presented here.
The photography used in the book since the first edition was graciously provided by Naoyuki Kurita of Tokyo, Japan. His website is a terrific resource for everyone.
Thank you for considering OITH for your library.
