Title: Great resource: refers to Vols 1 & 2
Review: I found the NSOG to be a treasure trove of objects and their locations. These two books will be used for many years. The descriptions are varied, as the observations were pulled from various observers. And the descriptions are listed by what size scope the viewer used. It is designed for larger scopes (12" and up), but there are many observations done with 6" to 10" scopes, even some 4" observations thrown in. These volumes, along with planning software, are at the center of my observation planning.
Is the review positive or negative?
