    New Zealand's Night Sky Glow in the Dark Chart
    By Stardome Observatory Auckland. Laminated folded chart, 0.035kgs,folded: 100mm x 210mm; Unfolded: 565mm x 210mm, full colour, published 2012.
    When you look up at the stars in the night sky it can be easy to think of them as lights glowing of some sort of large dark curved ceiling. It is impossible to distinguish whether you are looking at a bight star far away or a faint star much closer. The two stars of the Pointers Alpha and Beta Centauri appear about the same brightness, but the brighter one, Alpha Centauri, is the nearest to out Sun, and is 4.2 light years away 1 light-year is 9.5 trillion Kms!

    This beautifully presented fold out chart, which glows in the Dark, locates star patterns forJune 7pm (as per image on the right) and December 10pm. The reverse side has a legend of the Greek constellations and their meanings. A fabulous little guide for any night excursion away from the city lights!

    STAR CHART OF THE SOUTHERN SKIES.
    Poster, 722mm x 620mm.
    This chart depicts the night sky in autumn, as seen from 37 degrees South (New Zealand and southern Australia, South Africa and South America).
    This map shows the nigh sky as it appears at about 11pm local time in mid-April, 9pm in mid-May, and 7pm in mid-June. At these times the Southern Cross stands upright, dead south of the observer, and the Milky Way forms a great glowing arch across the sky.
    About 1000 stars have been shown - those of magnitude 4.5 or brighter. These correspond to the stars which may be seen easily from the suburbs of a large city on a clear, dark night. In rural areas, away from any artificial light, over 3600 stars are visible at any one time.

    Click for details of the Star Identifier
    BRITISH ADMIRALTY TYPE STAR IDENTIFIER
    This tool, like that above, is used to predict the bearing from true north (azimuth) and angle above the horizon (altitude) of the brightest stars. It is used for setting up star sights so that observations can be made using a firm horizon, by pre-setting the sextant and looking over the compass. In this way stars can be observed through the telescope before they are easily visible to the naked eye.
    Star sights using this technique are much more accurate than if taken when the sky is dark enough to recognise the stars in constellations with the naked eye, due to the superior quality of the horizon. The instructions provided with the identifier are explicit.
    Planets can also be pre-set using the identifier, enabling daylight sights of Venus and occasionally Mars and Jupiter.
    The main point of difference with the 2012-D above is the quality. The British Admiralty type has a card base-plate and wallet whilst the 2012-D is of strong plastic throughout.

    CAPTAIN RUDE STAR-FINDER 2102-D.
    The unit consists of a base plate (northern hemisphere on one side, southern on the other) plus a set of latitude plates. Use the nautical almanac to look up the Greenwich Hour Angle of Aries for the time of interest (usually Civil Twilight - also obtained from the nautical almanac), then set the closest latitude disk on the base plate. Rotate the arrow on the latitude disk to the Local Hour Angle of Aries on the graduated edge of the base-plate, and you have in your hand a picture of the sky around you, showing the stars visible at twilight. From the disk you can read the azimuths (bearings), and altitudes (angular height above the horizon) of the stars. The planets, sun and moon can be marked in pencil onto the base-plate for a specific date and their approximate positions in the sky obtained at the same time as the starts. This is an invaluable device for celestial navigators and also useful for more general star-gazing. The star-finder should be a complimentary tool to the sextant in any blue-water navigator's kit.
