You're invited to explore the autumn night sky with us at the SFA Observatory for our Public Night on Saturday, October 25, starting at 7:30 PM.

We will have several telescopes available for you to get an up-close look at the cosmos. The highlight of the evening will be a magnificent view of Saturn, where you'll be able to clearly see its beautiful rings.

Our guides will also host a laser-guided tour of the constellations and point our telescopes towards fascinating deep-sky objects. With the moon setting early, the sky will be dark and perfect for viewing distant wonders. Depending on conditions, we hope to show you:

*The Andromeda Galaxy (M31), the closest major galaxy to our own Milky Way, visible as a faint smudge to the naked eye and a grand spiral through a telescope.

*The Ring Nebula (M57), the ghostly, smoke-ring-like remnant of a star like our sun.

*The Pleiades Star Cluster (M45), also known as the Seven Sisters, a brilliant cluster of young, hot blue stars.

*The Double Cluster in Perseus, a stunning pair of open star clusters containing hundreds of stars.

This is a wonderful event for all ages and levels of experience.

Parking at the observatory is limited, so we do ask that you register in advance for a free ticket to help us manage attendance. Please reserve your spot at the Eventbrite link below:

It looks like the skies will be too cloudy to see objects with a telescope on Saturday night at the SFA Observatory. However, we would like to invite you to the SFA Planetarium this Saturday.

A solar eclipse is the only time we can see the outer atmosphere of the sun, the corona.
