"True Color" image of the heavily reddened HII region W3. Composed of JHK-band images coded as Blue, Green, and Red, respectively. Field of view is about 3-arcminutes on a side. Images reduced and combined into an image by Mike Merrill and Ian Gatley (NOAO) from data obtained UT 1996 Nov 20 with the NOAO 2.1-m telescope.


J-band image of NGC 7790 formed by a median combination of four 10-second integrations. Field of view is roughly 2.6-arcminutes, same orientation as above. The faintest star visible is about J=16.5. Images reduced by R. Pogge (OSU) from data obtained UT 1996 Sept 22 with the NOAO 2.1-m telescope.


K-band image of Saturn taken through a neutral density (0.5) filter. The planet appears dark because of methane absorption in the Saturn atmosphere, while the rings are icy and bright (and saturated). Images reduced by R. Pogge (OSU) from data obtained UT 1996 Sept 22 with the NOAO 2.1-m telescope.

A slitless K-band spectrum of Saturn taken by swapping in the K-band grism for the neutral density filter used in the direct image above. This shows the strong methane absorption bands in the Saturn atmosphere (smeared in resolution by the large size of the planet), and the reflected solar spectrum from the icy ring particles. Images reduced by R. Pogge (OSU) from data obtained UT 1996 Sept 22 with the NOAO 2.1-m telescope.


K-band slitless spectrum of the M2I star V717 Cygni. Although the spectroscopic mode has not yet been implemented, we did take a few slitless spectra with the K-band grism (using the normal K-band filter as an order sorting filter) to verify basic spectral operation. Implementation of the full spectroscopic mode will occur during later engineering runs this Fall. Images reduced by R. Pogge (OSU) from data obtained UT 1996 Sept 22 with the NOAO 2.1-m telescope.
