Telescope
UH 0.6m Telescope
In 1968, the first telescope on Mauna Kea. Photo courtesy of Bill Heacox.
• Operated manually by hand paddle.
• It’s not fully functional for researchers and students.
• Used for Instrumentation Testing.
The New 0.9m Telescope
• Upgraded to see
modern astronomical
images.
• Electronically controlled
from sea-level, UHHilo’s control room.
• Available for the research
of UH-Hilo students,
including
undergraduates.
