swuis

The Southwest Ultraviolet Imaging system (SWUIS) was based around a Maksutov-design ultraviolet (UV) telescope and a UV-sensitive, image-intensified Charge-Coupled Device (CCD) camera that frames at video frame rates. Scientists can obtain sensitive photometric measurements of astronomical targets. Payload on STS-93.

The primary objective of the first SWUIS Hale-Bopp Imaging experiment was
to obtain image sequences of Hale-Bopp to study its coma and tail
morphology and response to solar wind conditions during the
scientifically-interesting, classical turn-off phase as the comet moves
outbound beyond 2 AU.
