(More customer reviews)This is probably the best planisphere I have (I have 3) and very usable. It is usable both as a desk top study/planning tool and also out in the field. The front side of the planisphere that contains the sky mask is more suited for indoors use. The color-coded stars and red constellation lines are impossible to see in the dark with a red flashlight. However, this side is eminently suitable as a desk top planning tool given the tremendous wealth of detail and info.
The back side of the planisphere is unmasked and contains a very detailed sky map mainly for Norhern hemisphere users. This is blue-tone printed and is usable in the dark and the details show up well under a red flash light. An extra bonus are detailed markings of double stars, variable stars, all the Messier objects and selected NGC objects, such as the double cluster. The large size of the planisphere might be ergonomically inconvenient in the field and a little dorky looking, but hey it's virtually a star atlas with all the fabulous detail! After using this planisphere for a while, I picked up some of my others and they just look juvenile. I've gotten spoilt! I would say the next most decent planisphere is one of David Chandler's ( I like the distortion-free flip side Southern view option of his).
