Butterflies of Britain & Europe (collins Field Guide) by Richard Lewington

What lurks out there in the fog?
What was that eerie sound in the dead of night?
What flitted by at the end of the street, just beyond the farthest street lamp?

Here is a lunar atlas designed specifically for use in the field by lunar observers. Its title – The Six-inch Lunar Atlas – refers both to the aperture of the telescope used to make the images in the book, and also to the book’s physical size: so it’s perfect for fitting into an observer’s pocket!
