In addition to the main nebula and open clusters, this image also contains three smaller objects of interest:

Brey 55 is a Wolf-Rayet star that most likely causes the blue (mainly Oiii) ring-shaped nebula around it.

Brex 69 is a Wolf-Rayet star to the left of the blue nebula. Slightly to the south of the nebula’s center is a massive O2-type star (30 Dor 016), which is a runaway star from the main cluser in this image (Link).

The disk-shaped object in this image is an infrared source. There is not much known about it.
