The details of your growing record of double star observations can easily be kept in a spreadsheet with columns included for position angle, separation, magnitude, and color. Those entries provide the raw data needed to describe your stellar journeys. However, the essence of what draws you to doubles may not be as obvious when you review your notes. What inspires you to observe double stars? Is it the challenge of resolving a close pair, or pulling a faint secondary out of its companion’s glare? Or is it the stunning beauty of a colorful duo or closely matched twins? Do you enjoy tracking the progress of short-period doubles? All of these passions and more can be readily captured by sketches in a way that vividly supplements your tabular data.
