Star Trails +App
One of my hobbies is to take photographs of the stars, finding out that I wasn't great at shots of stars staying still I quickly changed to ones that move. So from there I've been taking local star trails.
With quite a few people asking me how it's done, I've gone and created an App that provides you with all of the information you need to know on how I create my photographs.
Download the App from the links below and learn how to make star trails when you are next out shooting the stars.
