Location of Polaris

To shoot many star trail photographs, it is important to understand where The North Star is in our night sky, the following blog entry explains where it is, you should then go and see for yourself :)This photograph is shot for a period of 8 Hours and shows the theoretical location of the North Pole; Polaris is shown in the small crescent shape to the left of the central point as it isn't placed at the directly above the North Pole, it is in fact around 1 Degree from the 'Northern Celestial Pole'

How to find Polaris?

The diagram above shows how to find The North Star quickly and easily by initially finding 'The Plough' or 'The Big Dipper' in the sky, then follow from the front of the 'scoop' at the same angle at whcih the scoop resides, until you reach Polaris, which will appear to have few stars surrounding it if you look closely enough. You ve found it! :)
