Stellar Associatons

[Starobserver]

I could need a little help on this one. 

I would like to observe and sketch the OB Associations, which are mentioned in some books I have (Observing Open Clusters by Mark Allison and Sky Vistas + Binocular Astronomy by Craig Crossen. The point however is, I cannot find a star-atlas or map where these associations can be found.... 

What I do have is a list of the OB associations with coordinates...  so when looking at the specific area (I also know the rough sizes of these associations), how do I know which stars in the field I am viewing belong actually to the association....  

Does anyone have a little more info or is there anyone out there who is experienced in viewing stellar associations?  

All help is welcome!

Cheers

Mathias

I just bought the book "Observer's Guide to Stellar Evolution' by Mike Inglis and it has a section on Stellar Associations which contains a table listing stellar associations, their descriptions and some of the individual stars they contain.  

I attached a couple iPhone photo's of the table.  Hopefully they come across as readable.  This is a good book it's  part observing guide which contains examples descriptions and charts and text book.   The Astro League Stellar Evolution Observing Program is based off of this book.  You can see the program and Stellar Evolution Object list here:
