Is it possible to create a great Observer’s Photographic Atlas of the Moon (OPAM)? I have most of Moon maps and atlases that have been published over the last 100 years, and none is exactly the companion I want at the telescope. Let me mention three good ones, that each miss for my needs. The Hatfield Photographic Lunar Atlas has many excellent attributes: it is not bulky, but is big enough to show a decent size area of the Moon, it has 5-6 views of each field, and it has sketch maps that identify all the named and lettered craters. Its downsides are that the photos are low resolution, 5-6 photos are too many while observing, and the map is very hard to read. During the last 3-5 years I have experimented with many ideas for a really useful OPAM - here is a summary: It should be spiral bound, have a limited number (30?) of sheets (a compromise of a relatively large area and large image scale), use high quality photos, and unambiguously display names of all major features. The image above shows a possible layout of a 32 sheet atlas and an image of map #2. I find a number of problems with this possible atlas design, but you can tell me what you like and don’t, and what you’d like for your perfect OPAM.

Boundaries of possible OPAM, shown on S&T’s map of the Lunar 100. Note that fields are meant to show a coherent geologic region and hence are of different sizes, but they would all be reproduced at the same scale. Opposite each map would be a page describing interesting features to oserve, as in a Norton’s Sky Atlas.
