Remarks: |
LBN 331 is a Ha emission nebula around the bright double star 32 Cygni,
close to Deneb. The image is strongly reminiscent of the
Veil Nebula (NGC 6960),
but in contrast to this it is not a supernova remnant, but a pure Ha
emission nebula without traces of OIII emission. |
Bemerkungen: |
LBN 331 ist ein Ha-Emissionsnebel rund um den hellen
Doppelstern 32 Cygni, ganz in der Nähe von Deneb gelegen. Das Bild erinnert
stark an den Schleiernebel
(NGC 6960), ist aber im Gegensatz zu diesem kein Supernova-Überrest,
sondern ein reiner Ha-Emissionsnebel ohne Spuren von OIII- Emission. |
