Why this book is useful:

If you are new to astronomy:

OITHv6.5 presents five ways of getting oriented with the night sky:
• Full-sky overviews
• Star Stories that bring constellations together for a "big picture" view
• Right ascension and Declination defined – 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 OITHv6.2 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.
• 752 total objects are mag 10 or brighter
• 196 object mag 7 and brighter
• 89 objects to mag 10.5
• 1.2020 RA/Dec data

If you only have binoculars:

• That's easy... there are 232 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
• The 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
• A new symbol has been added that better highlights red or carbon stars to ease the hunting in the maps

  have to say in these REVIEWS.

  "I have been observing for almost 40 years and this is the book that I have been waiting for. My observing style is view deep space objects by constellation. Your book will help me to observe completely before moving on to a the next constellation. Much thanks for a great design."
  Mike Baldassaro
  

If you have a dobsonian mount:

• The 75 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 for your red flashlight
• Find out quickly what you can actually see
• Objects are all viewable with a conventional telescope like a 6" reflector.
  89 challenges from mag10.1-10.5 are included; all suggested by readers as worthy 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 (1.2020) shows the addresses for objects in the area of view... saves sweeping time
• Low-tech... needs only a pencil
  
  

If you like other star maps like Sky Atlas 2000 or Pocket Sky Atlas:

• References to SA2K and PSA on each OITH map
• 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
  
  

  An exciting new way of observing the Moon!

  Aside from copious details on deep-sky objects, seven pages on viewing the Moon help make the book useful all month long.
  

"OITH is better than the reviews
& better than I thought it would be!"
