What are the best moon maps or lunar charts for using at the eyepiece? Or, would it be better to use one of the moon map apps and a smartphone/tablet for something like this? When observing the moon, one is hardly worried about maintaining dark adaptation and so the screen brightness shouldn't be too much of a problem. I just don't want to be dragging out a big or expensive book/chart only to have it damaged by the dew.
Also, what are some of the best reference moon maps/books/charts for when safely inside sitting at a desk?
