... STScI-PRC99-34a GETTING TO THE HEART OF A GALAXY This collage of images in visible and infrared light reveals how the barred spiral galaxy NGC 1365 is feeding material into its central region, igniting massive star birth and probably causing its bulge of stars to grow. The material also is fueling a black hole in the galaxy's core. ... In the infrared image at lower right, the Hubble telescope penetrates the dust seen in the WFPC2 picture to reveal more clusters of young stars. ...

Optical Filters . WFPC2 features two solar-blind Wood's filters, for FUV (<2000 ) imaging. ... These Wood's filters have a broad bandpass from 1200 to 2100 with visible-light transmission lower than 10^-8. ... In such cases, a Wood's filter (or "solar blind" detector as on STIS) is essential for FUV imaging so that the visible light leak does not dominate the observation. ... Two similar Wood's filters (F160AW and F160BW) were mounted in SOFA wheel 1 to provide some redundancy. ...

. This visible light wide-field image of the region around NGC 3582 was created from photographs taken through red and blue filters and forming part of the Digitized Sky Survey 2. The star formation region appears close to the center and is just one part of a vast complex of gas and dust in the southern Milky Way. The field of view is approximately 2.8 degrees across.
