YSU planetarium, CosmoQuest offer full-dome images

Youngstown State University’s Ward Beecher Planetarium is partnering with CosmoQuest to make available spectacular full-dome images that can be used for free by planetariums across the world.

“While there is now a large number of truly breath- taking full-dome planetarium shows available, there is clearly a need for low-cost, or even free, full-dome content to allow planetariums to stretch their programming capabilities,” said Pat Durrell, YSU professor of astronomy and director of the Ward Beecher Planetarium. “That’s what this project does.”

The project is called “Science on the Half Sphere” and is a collaboration between Ward Beecher Planetarium and CosmoQuest, a virtual-research facility.

The first product of the collaboration was a new full-dome planetarium show called “Cosmic Castaways,” which made its debut last fall at YSU’s Ward Beecher Planetarium. And, the project is announcing that a collection of nearly 60 full-dome, fisheye-lens images of the Mauna Kea Observatories on the island of Hawaii are available for downloading for free. Also available are nine short time-lapse, full-dome videos.

Mauna Kea, nearly 14,000 feet above sea level, is one of the best sites in the world for astronomical observation and includes more than a dozen large telescopes, Durrell said. He took still images and time-lapse sequences of the summit, the telescopes and the night sky in May 2012. Included are images from inside some of the largest telescopes in the world, such as the Canada-France-Hawaii Telescope, the Gemini North Telescope, the James-Clark Maxwell Telescope and the Harvard-CfA Submillimeter Array. The images were taken as part of a National Science Foundation research grant awarded to Durrell in 2009.

As a result of the project, the Ward Beecher Planetarium has a camera to use to take more full-dome images, he added.

The images are available on the CosmoQuest website at http://cosmoquest.org/blog/scienceonthehalfsphere/mauna-kea-images/ and http://cosmoquest.org/blog/scienceonthehalfsphere/mauna-kea-timelapses/.

The images were taken with a Canon 7D camera with a 5.6mm fisheye lens. Chicago- based Dome3D custom-built the camera system for YSU and provided training.

Images are provided as PNG images in three resolutions: 1024 ó1024 pixels, 2048 ó2048 pixels, and 4096 ó4096 pixels. The vast majority of the images were High Dynamic Range processed, from a combination of three bracketed exposures taken at different apertures.

YSU should develop complementary exchange programs with the Chabot Space & Science Center in Oakland.
