Why this book is useful:

If you are new to astronomy:

OITHv5.2 presents five ways of getting oriented with the night sky:
• Full-sky overview
• Star Stories that bring constellations together for a "big picture" view
• Right ascension and Declination – addresses in the sky
• Seasonal maps featuring the brightest objects
• Individual constellation maps with grids, stars and objects

The DETAILS, limited scope and ease of use are what set OITHv5.2 apart from other fieldbooks. Deep-sky objects are limited in magnitude (mag) to stay within reach of most small telescopes, even in somewhat light polluted skies.
722 total objects are mag 10 or brighter
187 object mag 7 and brighter
76 objects to mag 10.5
1.2011 RA/Dec data

ALL NEW in the 5th Edition:
an exciting new way of observing the Moon!

Aside from copious details on deep-sky objects, seven pages on viewing the Moon have been added to make OITHv5.2 useful all month long.

If you have binoculars:

  • That's easy... there are 155 binocular-class objects listed
  • A separate symbol is used in all the maps to designate the objects
  • At 5.5" x 8.5", OITH is sized to travel with you and be ready at a moment's notice
  • Fits in your car's glove compartment
  • New MOON viewing section will help you become more familiar with Earth's "night light"

If you are an experienced amateur:

  • OITH lists DSO's you may have missed (and aren't in many charts)
  • The book's size, coil binding, sketching rings and note pages make it convenient to carry and use at the scope
  • Observer information in the lists and other details could expand your viewing pleasure

If you have a dobsonian mount:

  • The 74 seasonal and constellation maps are set up so you can "slew and view" with purpose to let you work more on the objects
  • Finding the best sweeping areas is easy because the object-oriented maps display the patterns. Many neighboring objects are specially highlighted in the listings to help you find more DSO's

If you have a computerized scope:

  • No batteries required except your red flashlight
  • Find out quickly what you can actually see
  • Objects are all viewable with a conventional telescope, like a 6" reflector. 76 challenges from mag10.1-10.5 are included; all were suggested by readers as good targets
  • Most of the 35,000-125,000 (or more) objects in a typical 'scope computer are stars or objects too dim for a small telescope
  • The most current right ascension and declination data (1.2011) shows the addresses for objects in the area of view... saves sweeping time
  • Low-tech... needs only a pencil

If you like the big star maps:

  • OITH is a pocket-sized, on-the-lap, at-the-scope referral
  • Object-oriented maps are shown facing the listed descriptions to quickly pinpoint your search
  • This little book helps find objects in the big books
  • Numerous objects in OITH aren't in the big maps or in popular magazine lists
  • Fits in your glove compartment, gear bag or back pocket
