According to Avedisova this HII region is ionised by an uncatalogued B0.5 V star (MFJ Sh 2-294 4
). It contains the loose infrared star cluster [BDS2003] 95
which is divided into two sub-clusters, the denser one surrounding the ionising star.
Its odd shape looks like an upside down octopus - should it perhaps be called the Octopus nebula?
This detailed multiwavelength study gives a distance estimate of 4800 +/- 200 pc. [1
There is a double star cluster within this nebula, confirms the B0.5 V class ionising star at a distance of 3200 pc. [2
Contains the loose infrared star cluster [BDS2003] 95. [3
