Gemini Welcomes the New Year with "Wide Eyes"
December 19, 2006
A new series of images are now available that provide a "wide-eyed" view of the Gemini North telescope. The images were obtained as part of a program to capture a time-lapse sequence of the Gemini telescopes in operation during the course of one night. Each image shows a complete 180-degree view illuminated by moonlight (except for exterior views).
All images were obtained using a circular format fisheye lens and ~50 second exposures to simulate the naked-eye view of the telescope at night.

Star trail image of the Gemini laser guide star as it tracks along with the Earth's rotation. This image was made by stacking multiple 50-second exposures over a period of about 15 minutes. The remains of evening twilight can be seen to the right and the lights of Hilo to the left. Thanks to the Canada-France-Hawaii telescope for access to their catwalk for this image.
