abstract:

    line_1:        We propose high-resolution FOC f/288 imaging of the peculiar nucleus of
    line_2:        NGC1808. The nucleus of NGC1808 consists of several hot spots. Ground-based
    line_3:        observations show a star-like nucleus and two blue hot spots to the SE and NW
    line_4:        of the nucleus with reddish filaments. It has been concluded from
    line_5:        spectroscopic observations that the nuclear region of NGC1808 may consist of a
    line_6:        superposition of a normal HII region and a Seyfert-like nebulosity and that it
    line_7:        is very likely that NGC1808 has a Seyfert 2 nucleus. We wantto observe the
    line_8:        nuclear region with highest attainable spatial resolution at short UV
    line_9:        wavelengths in order to detect any anisotropic structure related to the
    line_10:       extra-nuclear activity. We want to deconvolve the f/288 images by the roll
    line_11:       deconvolution method in order to obtain diffraction-limited resolution in the
    line_12:       UV, for example 0.02" at lambda = 200nm.
