Obscura Society LA: Star Party at Mount Wilson

Step into the darkness with Obscura Society LA for an evening of planets, globular clusters, planetary nebulae, and colorful double stars at the Mt. Wilson Observatory

Collecting ancient light in a 60-inch mirror, the Hale Telescope reflects images in your eye of beautiful objects, some that lie millions of light years away from earth.

In 1903, astrophysicist George Ellery Hale went hiking in the San Gabriel Mountains. Resting at the summit of Mount Wilson, he gazed at his surroundings and realized he had found the perfect place to build an observatory. Five years later, at the very same spot, he revealed the world’s largest telescope, a 60-inch reflector that attracted preeminent scientists such as Albert Einstein and Edwin Hubble. In fact, it was with this telescope that Harlow Shapley discovered that the sun’s position was not the center of the Milky Way Galaxy.

Join the Obscura Society LA for an exclusive evening of observation with the historic 60-inch telescope. Assisted by a Telescope Operator and a Session Director, we will investigate objects in the night sky. What would YOU like to see? We are taking requests! A list of viewable objects will be provided, but you are encouraged to bring your own list. For the super astronomy nerds, be aware that the telescope cannot be pointed lower than 30° above the horizon, or beyond +75° or –26° declination.

Ticket sales will close on Wednesday October 29th for this event on Saturday December 13th! 

Notes for this adventure:

START TIME: The start time of this event has yet to be determined, but will be around 4:30. We will meet-up in La Cañada Flintridge around 3:30 to carpool up the mountain. The event will end at midnight. You MUST ARRIVE ON TIME, but you are welcome to leave early. Two weeks prior to the event, you will receive an email with the EXACT START TIME.

MANDATORY CARPOOLING: Due to limited parking, carpooling is mandatory. Two weeks prior to the event you will receive an email with the carpool meet-up location and detailed driving directions.

- CLOUDS AND CANCELLATION: This event is weather dependent. Attendees will be provided with a phone number to call the day of the event to confirm the status. It is your responsibility to confirm status.

- We cannot accommodate children under age twelve. All ticketed minor children must be accompanied by a ticketed responsible adult.

- Eat a large lunch before you come. You are also encouraged to bring snacks, just remember to bring enough to share! 

- It will be cold! Warm coats, sweaters, and hats are suggested. The dome is NOT heated.

- There may be mosquitoes! Feel free to bring bug spray.

- The 100 year old dome is not ADA compliant, and the telescope is inaccessible to those who cannot climb the thirty stairs to the observing deck. The Observatory is at 5,700 feet elevation, so anyone with serious breathing or heart problems probably should not attempt the trip.

- Photography is encouraged! Only rule is that the flash must be disabled when the dome lights are off for viewing. 

 - Bring a regular flashlight to use when leaving the dome to go to your car. The grounds are unlighted and are very uneven and hilly.

 - Alcohol is prohibited and no smoking or flames are allowed inside the dome at any time.

All ticket sales are final.
