2. Observations

The observations were made during two runs in December 1994 and July 1995 at La Silla with the Dutch 0.91 m and the 3.6 m telescope, respectively. At the Dutch 91 cm CCD # 33 with a TEK 512 chip (27 m pixels) was used. The spatial resolution is 0:0044/pixel. Two images of KeWe 1 each with an exposure of 10 min were obtained through filter #387 with a bandwidth of 81 Å and coadded. At the 3.6 m (back-up program) using the EFOSC 1 in imaging mode CCD # 26 with a TEK 512 chip with 27 m pixels was employed. In this case the resolution was 0:0061/pixel. For Wei 1-5 15 min exposures were obtained in the light of (filter #691, bandwidth 60 Å) and [O III ] (filter #686, bandwidth 59 Å). For KeWe 1 a 15 min [O III ] image was made.
