For the Drift Method, which can hold a star on station for many hours, You will need a low power eyepiece for your telescope with an illuminated reticle in the form of a double crosshair. You must choose two stars at the roughly the same declination but different Right Ascensions, one in the West, and one in the East. Here you will adjust the one in the West for East-West drift, and the one in the East for North-South drift. In both cases the idea is to keep the selected star from moving off a line parallel to the Celestial Equator for as long as possible. Pick a star near the meridian that is in the West close to the Celestial Equator at a declination neighboring 60° - 70°. It should not be similar to any other star in the vicinity, and should have a magnitude around 5 or 6. |
