The Gemini telescope and dome are ablaze in the setting sun's golden light. The reflections on the 8-m monolithic primary mirror are especially intricate and distorted. The shadow of the extinct 4200m Mauna Kea volcano can also be seen in the background upon a sea of clouds over the city of Hilo. The vertical shutters around the dome are usually opened at sunset to ensure that the inside and outside temperatures are the same throughout the night for greater image stability. Dr. Courteau has made extensive use of this telescope, and its twin in Chile, since his arrival at Queen's in 2004.
