Join the welcoming members of the Crawley Astronomical Society as they open the doors to their observatory on the grounds of Copthorne School.

You’ll enjoy a tour of the new facility and learn more about telescopes and how they work — if you have a telescope take it along for expert advice!

There will also be solar observing, an excellent opportunity to safely view our nearest star, the Sun, in incredible detail using a solar telescope. Finally, a bring-and-buy sale will have beginner telescopes and accessories available.

Event darkness

The Moon has a big impact on the visibility of celestial bodies in the night sky. Try to plan your stargazing when there is no bright Moon at night as this is when the skies will be at their darkest.

The below chart shows if and when the skies will be at their darkest during this event. Moonlight is shown in light yellow and the Sun's twilight in light blue. Midnight on the date shown is shown as a white line with sunset to the left and sunrise the next morning to the right. A black background with stars shows the best times for stargazing.
