These are from Brent Watson's "Finder Chart" series of books.
They are 8.5" x 5.5" books, printed black on white and are easily read in red light. The laminated pages are ring bound and lie flat, impervious to dew and crud, and won't blow away. Each book has an introduction describing the contents and use of the volume, as well as a table of contents for reference. Each object has a sky map with constellation lines ** and a Telrad target ** at the object location, with designations, type, description, magnitude, distance, size and diameter.
These are the most concise, portable, durable and useful sky charts you can get! Great for star hopping and very useful for goto observers too.
Small crease in binder on one volume, otherwise in like-new condition.
