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 a series of twelve 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.
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.
