Volume 1 charts from 90 deg north to 6 deg south.
Volume 2 charts from 6 deg north to 90 deg south.
Volume 3 has no charts and is catalog to all the DSOs in volumes 1 and 2. It does make finding things in vol 1 and 2 simpler.
A typical entry:
ra: 13 25 29
dec: -43 01 00
name: NGC 5128
mag: 6.8
dim(arcmin): 25.7 x 20.0
sb: 13.5
type: S0 pec
pa: 13.5
notes: Centaurus A. Wide dark lane.
A few examples from vol 3. For map 204 which includes NGC104, there are sections for galaxies, galaxy clusters, open clusters, globular clusters and bright nebulae. 207 has planetary nebulae. 208 has star clouds and dark nebulae.
You would not want to take "Uranometria" or "The Night Sky Observer's Guide" out into the field without a waterproof place to use them. They are both 3 volume sets, not cheap, hard back and heavy.
