Remarks: |
This quick shot (only 2h exposure) of some nebulosity in Cygnus shows up some interesting tiny nebulae, which are unnnamed (at least to our knowledge) except one: [P85b] 15, listed by V.M. Petrossian in his publication "New nebulous objects; Astrofizika 22, 423-424" (1985). Russian literature seems to be rather neglected in American astronomy literature. May be this is the reason we did not find a pdf file in the web, only the citation above. |
Bemerkungen: |
Diese kurze Aufnahme (nur 2h Belichtungszeit) einer Nebelregion in Cygnus zeigt einige interessante kleine Nebel, die (zumindest nach unserem Wissen) bis auf eine Ausnahme nicht benannt sind: [P85b] 15, aufgeführt von V.M. Petrossian in seiner Veröffentlichung "New nebulous objects; Astrofizika 22, 423-424" (1985). Die russische Literatur scheint in der amerikanischen Astronomieliteratur eher vernachlässigt zu werden. Wohl deswegen haben wir keine pdf-Datei im Web gefunden, sondern nur das obige Zitat. |
