Who this astronomy log is for
This log is for amateur astronomers and stargazers observing with telescopes, binoculars or just their eyes. It suits beginners learning the constellations, families watching meteor showers together and experienced observers working through lists of galaxies, nebulae and double stars. Recording what you saw, when, where and with which equipment builds skill and makes every clear night more rewarding, and your sketches become a personal record of the night sky.
How to use your astronomy log
Fill in an observing session page with date, location, sky conditions and seeing. Record each object on the observation log with equipment and magnification. Sketch what you see through the eyepiece. Keep a target list of objects to find. Follow the moon's phases in the moon journal. Note upcoming sky events such as eclipses and meteor showers. List your equipment, and save dark sky sites with notes on access and light pollution.
