A Brief Guide to Public Observing

Presenting the wonders of the night sky to the general public can be a rewarding experience. The smile on a child’s eyes they first time the see the rings of Saturn or the craters of The Moon is a truly a wonderful thing.

Public observing can also be a daunting challenge to the inexperienced public presenter. A little preparation and thought can prevent a lot of trouble and make it a better experience for both the presenter and the public.

I am attempting to put down a few of the things I have learned in over a decade of hauling a telescope around. In that time I have used countless schoolyards as observatories, set my gear up at posh resorts, on the tee line of a driving range, outside the front door of Wal-Mart, across the fence from cows at a dude ranch, parking lots, city sidewalks and grassy lawns, under conditions both perfect and absolutely lousy for doing astronomy. Dealt with everything from drunks to two year olds, and I still do this regularly… It is worth every young smile!

Laser Spirograph

With an upcoming open house, everyone around the observatory is frantically trying to get everything in place. There will be all manner of science exhibits throughout the observatory headquarters complex. Exhibits about our research, controlling the telescopes, an IR camera display (Get your portrait in IR!), liquid nitrogen ice-cream, just a lot of fun.

I am coordinating an exhibit we named Optics Lab… As you would expect, most of the exhibits in our area teach basic optics, light, lenses, etc. Understanding light and optics is a basic skill in a large observatory. We will have a few lenses on rails, a laser ray-trace table with acrylic lenses, an exhibit on polarization, and even a simple laser interferometer.

When attempting to teach something, a little eye-candy is helpful to catch the attention of the audience, particularly kids. Our group includes a laser engineer and a laser tech, so the use of lasers was obvious. There is little that catches the eyes of a kid faster than a bright laser beam. One of the first ideas they tossed on the table was a laser spirograph. After a few moments thought the answer was clear… I can build that!

Time to dig about in the scrap box! Actually more than a few boxes in my case, I am a bit of an electronics pack rat. A green laser module… Check! Small DC motors… Check! A few voltage regulators… Check! A couple potentiometers… Check! First surface mirrors… Check! In an hour of rummaging about I quickly located everything that was needed.

New Moon Saturday

A line of big telescopes greeted the crowd. Mike had his 20″, Cliff his 24″, my 18″ Deep Violet, later in the evening Olivier set up his 18″ Priscilla. All of this large glass was open to the public, we each had long line of folks waiting a turn at the eyepiece. It was a huge Saturday night crowd, several hundred people awaited darkness. Yes, I had made the decision to observe from the VIS, knowing that there would be a crowd, but wow!

Lots of folks wondered why there were so many telescopes. Over and over we explained that they were lucky, having chosen the right night to visit the mountain. A Saturday night close to the new moon, with local amateurs bringing their own telescopes to share.

Showpiece objects, the Andromeda Galaxy, The Pleiades and Jupiter were available for viewing. I was stuck on the Orion Nebula all evening long. I changed targets once, to meet a chorus of request to move back to the nebula. I have to admit it was a pretty view, even to me, who has seen this sight more times than I remember. I put the 35mm eyepiece in place, creating a bright low power view that had visitors waiting through line a few times for second and third looks.

In addition to the big dobs there were quite a few smaller ‘scopes present. Maureen had her C-11 setup, Larry brought his nice Stellarvue 102mm refractor, Mike had an 8″ SCT beside his 20″ for use by a friend. Dan didn’t bring a ‘scope, but he did bring pizza! We met Woody, an Alaskan Airlines pilot flying the Anchorage to Kona run. Out of a couple carry-on sized bags he produced more telescope than we would have thought fit in airline luggage…. A neat collapsible pier arrangement with an alt-az mount and a very nice WO 110mm APO.

Black Holes and the Fate of the Universe

This is a recoding of a Keck Observatory Astronomy Talk given by Dr. Günter Hasinger, Astronomer and Director of the University of Hawaii Institute for Astronomy. His talk, ‘Black Holes ad the Fate of the Universe’, was given on November 20, 2012 at the Gates Performing Arts Center at Hawaii Preparatory Academy, part of the W. M. Keck Observatory public lecture series.

It’s a little bit of the story of the Universe from beginning to end,” said Dr. Hasinger. “What role do black holes have on the fate of the universe, what are they, and how we can understand them better?”

Keck Week is Coming

W. M. Keck Observatory press release

This Spring, the W. M. Keck Observatory is throwing a weeklong party called Keck Week 2013, to celebrate the observatory’s first twenty years of high-impact, game-changing astronomical discoveries from the venerable twin-domes on the summit of Mauna Kea, Hawaii. The festivities will take place in several Kohala Coast resort venues as well as in the town of Kamuela and will mark a distinctive confluence of the brightest minds in astronomy alongside our country’s most significant scientific philanthropists. Early registration lasts until December 20th, offering a 30 percent discount off all events.

“We are very excited and honored to host Keck Week 2013,” said Taft Armandroff, Director of the W. M. Keck Observatory. “We look forward to showcasing the unprecedented discoveries made by our powerful telescopes and our ambitious community of dedicated scientists. With this event, we want to celebrate Keck’s first twenty years of achievements and unveil a vibrant course for our future.”

Keck Week 2013 will open March 14th at The Fairmont Orchid, with the Keck Observatory 20th Anniversary Science Meeting – a rare, two-day binge of astronomy discourse and finely honed presentations describing Keck’s legacy discoveries. On March 16th, Keck Week will peak with a Star Struck Fundraising Gala, a grand evening at the Four Seasons Resort Hualalai and feature a live auction of spectacular items, a gourmet dinner, live music and dancing, and remarks by special guests. Other events planned for Keck Week 2013 include:

  • “Astronomy Live! Tonight” – Enjoy a hosted reception under the stars with Keck’s most popular astronomers, star gazing, a live feed from the summit and much more;
  • “Welcome to Our Universe – Keck Observatory’s Open House” – Explore and discover the science and engineering of the Keck Observatory with exhibits and hands-on activities developed by the professional staff at Keck;
  • Keck Tennis Match – Watch Keck astronomers out-parallax their Friends of Keck competitors on the court;
  • Contact! – A free showing of the feature film on the big screen; and
  • Hawai’i Astronomy – Visit Hawai’i’s other astronomical centers.
