Huge collection of #blue stars, one definite #open cluster, probably others belong to an association.
Associations like this are often tricky. Tons of young stars, but often few clusters -- which is interesting science we're studying!
Correct ! :-D
It can be a type of open cluster, but still too much spread. So those blue stars maybe in a giant HII region where many stars are forming.
See 'the guide' at the home page (at the end) : http://www.andromedaproject.org/#!/guide/type/star-clusters
Top right corner looks like a cluster, but a lot of the very blue spots are probably HII regions.
Help! I have no idea how to classify all these blue spots! I checked 11 cluster at random, I guess it is not right at all.
