Dew-Resistant Messier Card

This 12" x 9" quick-reference sky chart shows the location of all 109 Messier objects on the front, a great help for binocular astronomers. It tabulates their epoch 2000.0 coordinates, sizes, apparent visual magnitudes, type, constellation, common names, and NGC/IC catalog numbers on the back for telescope astronomers with equatorial and go-to mounts. It also contains notes on the best sequence to use to observe a Messier marathon. It is made of heavy-gauge synthetic stock, not paper, that has been treated to be dew resistant so it will give you years of use out in the field. (And you'll find you will be using this handy guide often, not just when Messier marathon time rolls around.)
