• Spectra of 21 planetary nebulae in NGC 5128 (Centaurus-A) with VLT FORS2.

  Multi-object spectra taken with the multi-slit mode of VLT FORS2 of planetary nebulae in the nearest giant elliptical galaxy NGC 5128. Although there are only 18 slitlets, 21 planetary nebulae were detected. The strongest lines around the centre of the spectrum (wavelengths increase from left to to right) are [O III]4959 and 5007A. An extracted spectrum of the bright planetary nebulae catalogued as 5601 by Hui et al (ApJS, 88, 423, 1993) is shown. The [O III]4363A electron temperature sensitive line is detected.

• 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.
