• VLT spectra of planetary nebulae in NGC 5128 (Centaurus-A).

  Multi-object spectra taken with the multi-slit mode of VLT FORS2 of planetary nebulae in the nearest giant elliptical galaxy NGC 5128. The strongest lines around the centre of the spectrum are [O III]4959 and 5007Å. An extracted spectrum of the bright planetary nebulae catalogued as 5601 by Hui et al (ApJS, 88, 423, 1993) is shown. The full paper describes the results for 51 PN and analysis of the abundances.

• High resolution combination of WFPC2 images of Orion nebula

  Fifteen archive images in four filters ([O III], H-alpha, [N II] and narrow V) of the core of the Orion nebula (NGC 1976) (see O'Dell & Wong, AJ, 111, 846, 1996) were combined using the drizzle technique of image combination to produce a mosaic with a resolution of 0.1'' over the whole field. The images are available.
