To improve your observing skills To create a visual record To exercise your creativity Why Sketch?

Historical Background These are just a few of the many past astronomers who were keen observers and who sketched their observations: Galileo Huygens Maraldi W.C. Bond & G.P. Bond Antoniadi Dawes Barnard

Galileo Galileo published his observations of Jupiter and its moons in SideriusNuncius, The Starry Messenger (1610). This is an excerpt from his journal. Source: Galileo Project/Al Van Helden

Galileo Galileo and his protégé Castelli developed solar projection to accurately observe and record sunspots . Through a sequence of solar observations, Galileo demonstrated the rotation of the Sun. Source: Galileo Project/Al Van Helden

Huygens Another pioneer in the mid-17th century was Christiaan Huygens , who made these observations of Mars Source: The Exploration of Mars By Werner von Braun & ChesleyBonestell

Maraldi From 1672 to 1719, Maraldi made many observations of Mars and made careful measurements of the polar ice cap. Source: The Exploration of Mars By Werner von Braun & ChesleyBonestell

Antoniadi By the 19th and early 20th century, improved telescopes were allowing skilled observers to make even more detailed sketches of celestial objects. Source: The Planet Mars by William Sheehan

What makes a good astro sketch? Record what you see—not what you would like to seeInclude information such as instrument used, magnification, and field of view (FOV) Include time and date (UT), cardinal directions, seeing, transparency, altitude of object, and any other relevant information Add any other notes you feel are pertinent to your observation
