LPOD - Lunar Photo of the Day

A carefully selected list of 100 interesting places to look for on the Moon - excellent idea!  Accompanied by monthly articles by Dr Wood in Sky and Telescope

Excellent book, packed with information, going through the main features day-by-day at the terminator, and lots more ... and another book on the way! Not expensive but very useful for observers.   Author writes the Moonwatch column in 'Astronomy Now' and edits the Popular Astronomy magazine

Peter's latest Moon book is now out 'The Moon - and how to observe it'  274pp published by Springer

I like this book very much - it has all sorts of information on the various measurements of the Moon, its origins, the fascinating comparisons with other moons, and a huge section going over the areas of the Moon in detail - plus lots more. Of interest to binocular/naked eye viewers is the section on the Lunar Showcase, a list of places to visit. The book complements both his Observer's Guide (see above) and Charles Wood's Modern Moon (see below) - these books along with Rükl's Atlas are my main guides to the Moon at present.

Check out his website for book details and SPA Lunar section information : www.lunarobservers.com

Britain's best known astronomer's observational  book on the Moon (2001)

Clear, day-by-day explanations of the main features to be seen each day at the terminator.  Easy to use. 

Finally tracked it down in the UK from SCS Astro. Expensive - but excellent.  Written with authority by someone who has spent many years studying the Moon and  its geology.   Pleasurable reading.  Author writes Lunar column in 'Sky and Telescope' magazine

I've frequently use maps by Rukl that come in other books - this Atlas gives the beautifully drawn maps in a bigger format - sometimes too big for my small telescope.  Fairly expensive but a beautiful, useful atlas.

Large book, serious geology, very interesting, very big - available in  pdf chunks

Slim (64 pages) beginner's book .  Gives  practical data on telescopes, eye relief etc.  Has libration charts (till 2007 in mine).  But most of the book concerns 31 'objects' for you to find through the moon's sequence - with detailed, delicate drawings for each. I've seen copies in the remainder shops - a bargain!!

Great program with lots of ephemeris details, libration, terminator features and much more - even more stuff if you register

Cruise over the surface of the moon at satellite height.  See the geographical features with the USGS maps - high places, low spots;  fly round the far side;  see the Clementine features.  Comes with the satellite viewing of the Earth.  Great fun!!
