5 MeWe1-5, MeWe1-8, and MeWe1-9

  The three PNe MeWe1-5, MeWe1-8, and MeWe1-9 were found by Melmer & Weinberger (1990) by an inspection of ESOR/SERCJ films. They have been verified to be true PNe by spectra taken with the ESO B&C spectrograph (see Acker et al. 1992).

  

Figure 2: MeWe1-5. The PN is very faint and appears just above the background. Its central star cannot be identified

On our images, MeWe1-5 appears just above the background with a faint arc on the western side (Fig.2). MeWe1-8 (Fig.3) and MeWe1-9 (Fig.4) are circular PNe with no distinct central hole.

Although the central star of MeWe1-5 has a brightness m_B=20.6 (Melmer & Weinberger 1990) which is not much fainter than that of the central star of MeWe1-8 (m_B=20.3), it can, in contrast, not be identified on our narrow-band images. In the case of MeWe1-9, we cannot identify its central star (m_B=21.9), too.
