The images of NGC 253  wer obtained 23 Nov 1999 using the Keck I telescope under cirrus conditions and vaiable seeing.  The images are  unprocessed other than the  summation of all of the chop pair differences and combining of dither patterns.  The total on source integration time was 800 sec for the 8.0 µm data and 400 sec for the 12.5µm data.


RY Scuti, Massive Binary System with Mass-Loss Wind

The image of RY Scuti  above was obtained 30 Aug 1999 using the Keck I telescope.  The image is  unprocessed other than the  summation of all of the chop pair differences and stretched to enhance the contrast.  The total on source integration time was 216 sec and was obtained in the chop-nod observing mode.

The images above were obtained on 31May1999 using the Keck I telescope. They are unprocessed other than the  summation of all of the chop pair differences and stretched to enhance the contrast.  The on source integration time was 160 sec per image. The images were obtained in the chop-nod observing mode.  It should noted that these images were obtained under poor weather conditions that included cirrus cloud cover and high humidity.

The image of IC 418 was obtained on 26 Feb 1999 using the Keck I telescope. It is a combination of two images dithered about 3 arcsec apart to help cover the extent of the object. The image is  unprocessed other than the  summation of all of the chop pair differences and stretched to enhance the contrast.  The total on source integration time was 160 sec and was obtained in the chop-nod observing mode.


Saturn

The image of Saturn was obtained on 31 Oct 1998 during "First Light" experiments with newly upgraded LWS. It is a combination of several images dithered to help cover the extent of the object. The image has been smoothed to fill in some gaps not covered by the dither pattern and has been stretched to enhance the contrast.
