Composite view showing the Northern 2MASS Telescope being lifted
into its dome on Mt. Hopkins (upper left); three-color image
of the planetary nebula M57, the Ring Nebula, taken on the first night of
2MASS operations
(upper right); and the Northern Telescope ready for operation at
sunset on Mt. Hopkins (bottom).
The Northern 2MASS Telescope being lifted into its dome on Mt Hopkins, AZ
on January 21, 1997. The telescope was constructed by M3 Engineering
(Tucson, AZ) under the direction of 2MASS Project Manager Rae Stiening
of the Univ. of Massachussetts. The classical cassegrain design
utilizes a 1.3 meter primary mirror that was figured by Rayleigh Optical
(Tucson, AZ).
Operational Northern 2MASS Telescope on Mt. Hopkins, AZ. The
gold cylinder attached to the bottom of the telescope is the
2MASS Survey Camera. The Survey Camera contains three array detectors
that image the sky simultaneously in three wavelengths of infrared
light. The camera was designed and constructed by Telic Optics
under the direction of 2MASS Principal Investigator, Dr. Michael Skrutskie
of the Univ. of Massachussetts.
The building for the Operational Southern 2MASS Telescope at Cerro Tololo (CTIO) in Chile. The facility is just below the summit of Cerro Tololo,
down the hill from the 4-m telescope. The southern
telescope is identical to the one at Mt. Hopkins and is equipped
with an identical camera.
