LBN 248 (also named DWB 84) is an emission and reflection nebula in
constellation Cygnus. Dolidze 6, a dubious candidate for an open star cluster can be found in the centre of the above image. Inside of Dolidze 6 one can find the BD+40°4124 cluster, a small group of very young stars (age < 0.5 mio years). The brightest members of this small cluster are three Herbig Ae/Be stars:
As a result of the intense interstellar extinction most of the stars of the BD+40°4124 cluster are only visible in infrared light. |
