A low-to-moderate-resolution spectrometer (R = 600-2,500) for faint object
work available with TI1
and CC1
CCDs. Various gratings provide wavelength coverage from 0.3 to 1.1 microns.
The LCS has long slit (150") capability and CCD-based guiding and acquisition
using the Star
1 guider. Limiting magnitude mv = 20. The TI1
CCD has better QE at all wavelengths but suffers from severe fringing for
wavelengths redward of 6000A; thus for red work, CC1
is the better choice. Both chips can be used all the way to the atmospheric
cutoff, but TI1
is better than CC1
in the blue.
