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! The author’s own lunar photographs were taken
with a 6-inch (150mm) telescope and CCD camera, and closely match the
visual appearance of the Moon when viewed through a modest (3-inch to
8-inch) telescope. (Depending on seeing, of course.) Each picture is
shown oriented "as the Moon really is" when viewed from the northern
hemisphere, and is supplemented by exquisite computer sketches that
list the main features. Two separate computer sketches are provided to
go with each photograph, one oriented to appear as seen through an SCT
telescope (e.g. the Meade and Celestron ranges), the other oriented for
Newtonian and refracting telescopes. It is worth commenting that most
observers find it extremely difficult to identify lunar features when
using a conventional atlas and SCT telescope – the human brain is very
poor at making "mirror-image" visual translations. There is a page of descriptions for the salient features in each photograph. Finally,
an index at the end of the book lists all the features identified, and
gives their approximate height, depth and for crater, diameter.
