ASAS Gallery - Equipment
The ASAS-3 system, as of August 2000.
The 10-inch astrograph dome of the Las Campanas Observatory, in which
ASAS-3 was installed in August 2000.
The ASAS mount, a horse-shoe design driven in both axes by the stepper motors.
Same as above, in grey.
Two wide-field telescopes, each equipped with 200/2.8 Minolta telephoto
lens and 2Kx2K AP-10 CCD camera (made by Apogee Inc), covering 8.8x8.8 deg
of the sky through the V and I filters.
Narrow-field telescope is F=750mm, D=250mm, F/3.3 Cassegrain-like instrument
with 3-element Wyne corrector. It has the same 2Kx2K AP-10 CDD camera and I
filter. FOV is 2.2x 2.2 deg, but correct PSF (FWHM < 2.5 pixels) is currently
available only inside the circular field of ~1 deg radius.
A very-wide-field telescope equipped with the 50 mm lens and another
AP-10 camera. It features 36x26 deg. FOV and observes only a few selected
fields in purpose to test instrument sensitivity for fast transient events.
All four instruments of the ASAS-3 system, as of April, 2002.
The new automated ASAS-3 enclosure, to which the system was moved in April 2002.
The enclosure, closed.
Shells of the enclosure are driven by off-the-shelf gate-motors.
A stable rack inside the enclosure, housing the computers on its bottom level
and telescopes on the upper.
Small telescope focusing.
Large telescope focusing.
