This year the Astronomy Calendar again features the winners of the CWAS David Malin Awards.
The calendar provides a nightly guide to what’s visible in the sky, including moon phases, planetary positions, eclipses, lunar occultations, conjunctions and meteor showers.
It includes a summary of the year indicating the best times to view the planets.
Calendar features nightly moon phases and Monthly Star maps and is 23 x 33cm in size, opening to 46 x33cm.
Maps have been designed for 25° to 45° south latitude.
This thermometer allows you to see the temperature by watching the balls sink and float in a beautiful sealed glass cylinder, as their densities are such that they rise or fall as the temperature changes. You can hang this one up as a beautiful display piece.
Measures between 16°C and 32°C
