Polaris Celestial Sight Form. Astro Navigation Sight Reduction Form.
The Pole star (Polaris) is easy to find, the sight is easy to work out and the satisfying result is a very useful line of latitude. Easy.
Sometimes considered a black art, Celestial Navigation, also known as Astro Navigation, is actually quite 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 now need to do is some simple addition or subtraction.
The form is A4 in size and has a Matt Encapsulation. One side shows a completed example with notes explaining how the information found and what to do with it. It goes on to show how to use that information. The format provides a great memory jogger for those who have used Celestial Navigation in the past are now a little rusty.
This Sight Reduction Form is designed to be used with the Nautical Almanac. It can be written on with a soft 2B pencil.
The colour of the card may differ from the image.
