Planet Celestial Navigation Sight Form

Guiding you through the sight reduction process for the Planets:- Venus, Mars, Jupiter and Saturn.

Matt Encapsulated A4 Sight Reduction form. One side has a completed example with notes explaining where the information is obtained from and shows how it is used.

Although often considered a black art, Celestial Navigation, also known as Astro Navigation, is actually pretty straightforward.  Using a sextant is simply a matter of a bit of practice. The Sight Reduction part is all about locating information and noting it somewhere sensible, which is where this helpful series of Sight Reduction Forms comes in. All you need to do then is some simple addition or subtraction.

The Planet Celestial Navigation Form is designed for use with the Rapid Sight Reduction Tables NP303. Vol. 2 (latitudes 0-40 degrees) or NP303 Vol. 3 (latitudes 39-89 degrees) previously called the Air Tables AP3270. Vol. 2 or 3 and the Nautical Almanac.

Others in the series included  the Sun, Sun Meridian Passage, the Moon, Polaris, Stars, Selected Stars and Compass Deviation Check.

This Sight Reduction Form can be written on with 2B pencil and erased using a soft eraser.
NB. Colour of card may differ from image.
