DEEP SKY OBSERVING
by Mark Wagner

July 2007 third quarter to new moon observing list. Primary targets are generally easy. Secondary targets range from more difficult (in bold) to very difficult and are near the primary targets as you star hop. The list begins in the north and moves southward. Objects are within roughly a two hour section of right ascension that is at a comfortable elevation the east at astronomical dark.
