A New Atlas?
A New Atlas?
In the LPOD of
, 2007 I proposed that a group of imagers could contribute a consistent set of images that would become the core of a new
Observer's Photographic Atlas of the Moon
. This page is a forum to collect ideas and comments about the need for a new atlas, its desired characteristics, and other relevant topics. This is a wiki so its easy for you to add text to this page or to use the "discussion" tab above for more lengthy comments. Jump in! Chuck Wood
This page might be the spark which ignited the creation of the wonderful and handy
21st Century Atlas of the Moon
by C.A.Wood and M.Collins.

1: Is there a need for a new photographic lunar atlas?
Yes. The currently available ones (table below) all were created to satisfy their authors, but they don't work for me for the reasons listed as comments. In the table "Sections" is the number of pieces the Moon is divided into, and "Pages" is the number of pages showing the Moon (multiple illumination views). "Names" means that the atlas identifies named craters, and "Letters" means it also shows lettered craters. "Copernicus" is the diameter in mm of Copernicus to indicate scale. Rükl's non-photographic
is added for comparison.
Table to be completed/added to.
low res images, convenient size
Legault & Brunier
small scale, too large
Chong, Lim & Ang
small scale, some overexposed images
large scale, selected closeups
poor res, awkward arrangement
Bussey & Spudis
inconstant illumination, spacecraft view
heavy, expensive, large scale, variable scale
In reviewing these atlases it seems my greatest problems with them are scale and resolution - half have too small of scale (image size) and others are too large, and resolutions are too low for most. The last four divide the Moon into too many sections - especially awkward at the telescope. Hatfield seems the best in terms of image (except for resolution), and Legault & Brunier is best for layout (except too big).
2: What are desired characteristics of a new observer's photographic atlas?
Moderate to high resolution
Single view adequate (and more do-able)
Names, not letters
Sections have geologically significant boundaries
Smaller scale synoptic map of each basin
Closeup images of selected features
Good descriptions of selected features
Lat/Long - not necessary - maybe?
Good libration supplemental limb views
Spiral binding (to open flat)
Long axis vertical - along terminator
Coated paper to prevent moisture damage

Normal and mirror-reversed views?
Dec 3, 2007
Slight overlap of maps with a spiral binding as in S&T's Pocket Sky Atlas
More ideas are in the
I would imagine that the central sections of the atlas would produce good images which show shadow relief views of the surface features. What about the areas towards the limb. I should imagine that these areas would need to be of multiple images over a number of days as the terminator crosses the Moon? Dave Storey. 3rd Dec. 2007
Are you interested in acquiring suitable images of the quality needed of these areas - or whatever ones are decided on?
Certainly would like to do some areas but I do lack the equipment that some of LPOD observers use and they do produce excellent images.
