As each month passes, the sun "moves" to a new sign of the zodiac, and our evening sky reveals a new region of the universe for us to explore. This year we are offering monthly evenings of exploration at RFO, called "Your Universe". Each month will be dedicated to a different zodiacal constellation, its neighbors, planets, prominent deep space objects, and just enough astrophysics to bring it together.
Please note that this event starts on time with a presentation. Please account for extra time driving up the mountain and parking.
After the classroom program, weather permitting, we will step out under beautiful dark skies to locate the constellations and other objects discussed. Then we will move to RFO's three main telescopes (an 8" refractor, a 40" reflector, and a 20" astrophotography system) for deeper examinations. Sales are limited to 35 guests so we can provide a more personal experience. You will have plenty of time at the telescope eyepieces, and as always, the observatory will be staffed by knowledgeable and enthusiastic volunteers eager to show you the night sights, and answer any questions you may have.
Please join us for this year's trip around the Sun and learn more about "Your Universe".
$50.00 per adult, $45 for students and seniors (62+) and $40 for members. Sugarloaf Ridge State Park parking fees are included.
Classes are held at The Robert Ferguson Observatory. You do not need to pay the park day use fee to attend the class.
You MUST have a ticket to attend this event. Attendance is limited. Please note that tickets are non-refundable and cannot be used for future events.
Please note, members receive a 20% discount. If you'd like to become a member, please fill out a member application form and you will be sent a promotional code to use when purchasing tickets.
