1. Observing capabilities
... NICS will be the only infrared instrument for the first light of the TNG; as a consequence, we decided to incorporate a sufficient degree of operation flexibility by providing the instrument with six different observing modes, three aimed at imaging and three at spectroscopy: . ... It will be possible to use the narrow band filters as order sorters; this will allow to perform high resolution long-slit spectroscopy in the wavelength ranges covered by the available narrow band filters. ...

2. Observing with Linear Ramp Filters
The Linear Ramp Filters (LRFs) provide a narrow band ( ) imaging capability which is continuously tunable from 3710е to 9762е. These are essentially a collection of narrow band interference filters whose central wavelength varies with position on the filter glass. ... If it is necessary to know which CCD will be used, observers can consult Table 3.7 or Table 3.8 , or use the on-line LRF calculator tool on the WFPC2 WWW pages. ... See Linear Ramp Filters for further details on LRFs.) ...

4. IR All-Sky Camera
Sloan Digital Sky Survey Telescope Technical Note 19910801 . ... It has long been apparent that an all-sky picture of clouds over an observatory site and available in near real-time would be a great benefit to personnel using a telescope. ... We have anecdotal evidence from J.T. Williams of MMTO and David Westfall, formerly of CFHT and now of New Mexico Institute of Mining, that video-rate 10 micron cameras are very effective at imaging clouds. ... The focal length of the mirror is 25 mm. ...
