      PLN-NL – Dutch Planisfeer voor 52° noord

      The perfect way to learn how to recognise the stars and constellations, very accurate between 47° and 57° north latitude

      by Rob Walrecht

      A Planisphere or ‘Star Wheel’ is the perfect way to learn how to recognise the stars and constellations. It consists of a star chart showing all stars and constellations that are visible from a certain area (latitude). However, stars rise and set and the Night Sky changes from season to season. Therefore a second disc is placed on top of the star chart, containing a ‘horizon’ that defines the visible part of the sky at any given moment, which is naturally half of the total starry sky. That moment can be set at the desired date and time. Rob Walrecht’s planisphere design is very modern and attractive. His planispheres are among the best in the world. His programme is the most extensive in the world, with English planispheres for the entire populated world, and planispheres in thirteen other languages (in 2013). The basic star chart contains some 700 stars and 300 ‘objects for binoculars’: galaxies, nebulae, open and globular clusters, double and variable stars that can be seen with the naked eye or at least with binoculars. This is a Dutch language planisphere for 52° north, perfect anywhere between 47° and 57° north, so perfect for the Netherlands and Belgium. It is a square design, 25 x 25 cm, folded and with four pages: one with the star chart/upper disc, one with instructions and a few interesting tips and two (the inside pages) containing a concise introduction to astronomy. For use in for instance: Central European latitudes, Northern USA, Southern Canada and Central Asia. Rob Walrecht Productions is specialised in customised planispheres, so you can have one for any latitude zone, in any language, in any size, shape and colours, and in any design.

      Solar System Scale Model 1:100 billion (US edition)

      The perfect tool to learn all about our Solar System

      by Rob Walrecht

      This unique product is both a scale model and concise encyclopaedia of the Solar System in one! It consists of sixteen information-packed cards (10x12 cm or 4x5 inch), all pertaining to the Sun, the planets, the Moon, asteroids, comets and the new class to which Pluto now belongs, the dwarf planets. These cards are a quick way to learn all there is to know about these objects, as well as being ideal for youngsters, papers and talks! Primarily, however, it is an exquisite scale model (scale 1:100 billion) of our fascinating Solar System, presenting the best possible representation of the distances within our Solar System as well as the unimaginable emptiness of the universe. This version is made for US customers, as the units used are inches, miles, Fahrenheit etc. In this scale model, the Sun is the size of a marble (14 mm), Jupiter, which is at 8 m/26 ft from the Sun, as large as a plastic pin-head, the Earth (at 1.5 m/5 ft) as large a grain of coarse sand, Mars (at 2.3 m/7.5 ft) as large a grain of fine sand and Pluto, which would now be at 47 m/155 ft from the Sun, as large as a dust particle... The scale model, when completely placed, is 64 m (210 ft) long. The closest next star is at 400 km (250 miles) from the Sun! The cards show the sizes of the Heavenly bodies at scale, as well as these sizes one hundred times ‘enlarged’, for better comparison of the members of our Solar System. Special standards to place them are included and the cards contain holes to be hung on the wall or from sticks. Available are an English version (with metric units), a US version (with inches, miles, Fahrenheit etc.) and a Dutch version.

      New Perspectives in Cultural Astronomy

      by Clive Ruggles (Editor) , Gary Urton (Editor)

      Compiled in honour of Anthony F Aveni, America's leading archaeoastronomer, this book offers state-of-the-art work in cultural astronomy by well-known experts in Mayan glyphic studies, cultural history, ethnohistory, and the history of science and of religions. This collection's wide range of outstanding scholarship reveals that cultural astronomy has come into its own. The diverse topics addressed by the contributors include the correlation between Colonial Northern Zapotec and Gregorian calendars, the period of use of the Dresden Codex Venus table and the significance of the Lunar Almanacs that precede it, a new interpretation of an Inka tapestry mantle as a commemorative calendar, temple orientations in Hawai'i and church orientations in Medieval England, and the connection in cultural imagery between astronomers (science) and wizards (magic). Contributors include: Harvey M Bricker; Victoria R Bricker; Edward E Calnek; Clemency Coggins; John Justeson; Edwin C Krupp; Stephen C McCluskey; Susan Milbrath; Clive Ruggles; David Tavà rez; Barbara Tedlock; Dennis Tedlock; Gary Urton and R Tom Zuidema.

      Genieten van de sterrenhemel

      ('Enjoying the Night Sky')

      by Rob Walrecht

      Covering everything that everyone should know about astronomy as it influences our daily lives: the day, the year, the seasons, the changing of the Moon’s ‘shape’, how the planets we see in the sky move, about the time we use, our calendar, the tides. There are chapters about the Solar System, and stars and the Milky Way, subjects that are much more extensively treated in parts 2 and 3. Including much background information about constellations and star charts, and planispheres in particular. Also contains a wonderful observation programme per season, for the layman. It basically covers the heavens as we can observe it from Earth. First part of series of three, about astronomy (Enjoying Astronomy), for the general public. They are also useful as books for astronomy courses, and written for 12-14 years and up. About 100 wonderful pictures and 90 illustrations.
