| Exposure date: | October 25th/26th, 2003 |
| Location: | Capella Observatory at Amani Lodge, Kupferberg near Windhoek, Namibia |
| Filter: | FR03 + Astronomik Typ II LRGB filters |
| Instrument: | Ganymed 60cm-Hypergraph in secondary focus, f=4800 mm |

| Photographer: | Josef Pöpsel |
| Remarks: | The main reason for the very short sub exposure time (60 and 120 sec., resp.) was to avoid blooming of the 10 mag bright star below the PN. In the original images the star was above the PN. |
| Bemerkungen: | Der Hauptgrund für die sehr kurze Belichtungszeit der Einzelaufnahmen (60 bzw. 120 sec.) war, das Blooming des 10 mag hellen Sterns unter dem PN zu verhindern. In den Originalbildern ist der Stern über dem PN. |
