Observing the Sky from 40°N
This atlas contains a set of 24 maps regulated to the latitude of 40°N, similar to those of many important cities in the northern hemisphere, such as New York, Washington D.C., Boulder, San Francisco, Rome, Madrid, Beijing and Tokyo, as well as information about some double and variable stars and almost 160 deep sky objects.
These maps can be used also from latitudes between 45°N and 35°N without any notable difference.
8 selected areas of the sky suitable for binoculars are displayed in separated and detailed maps, followed by a short description of those galactic regions.
