    CCD Imaging of NGC4861 - Morphology and Brightness Distribution
    We discuss narrow band CCD imaging of NGC 4861 in continua at 4500 A, 5300 A and 6300 A as well as in Hα, Hβ and (O III] λ5007 A lines. We find that the system...

    CCD photometry of the metal-rich halo cluster NGC 6366.
    We present new BV photometry for 6564 stars in the field of the globular cluster NGC 6366, using a wide field CCD camera at the prime focus of the Isaac Newton...

    CCD-based observations of PG 0856+121 and a theoretical analysis of its oscillation modes
    BVRI CCD-based and near-IR (J) imaging, together with unfiltered photometry of the hot subdwarf B star PG 0856+121, are reported. Two close, faint, red, point...

    Census of H II regions in NGC 6754 derived with MUSE: Constraints on the metal mixing scale
    We present a study of the H II regions in the galaxy NGC 6754 from a two pointing mosaic comprising 197 637 individual spectra, using integral field...

    Center-to-limb variation of solar line profiles as a test of NLTE line formation calculations
    We present new observations of the center-to-limb variation of spectral lines in the quiet Sun. Our long-slit spectra are corrected for scattered light, which...

    Center-to-limb variation of the area covered by magnetic bright points in the quiet Sun
    Context. The quiet Sun magnetic fields produce ubiquitous bright points (BPs) that cover a significant fraction of the solar surface. Their contribution to the...

    Central star formation and metallicity in CALIFA interacting galaxies
    We use optical integral-field spectroscopic (IFS) data from 103 nearby galaxies at different stages of the merging event, from close pairs to merger remnants...
