When we look at the band of the Milky Way, what portion of it are we looking at? Are we looking inward towards the galactic core and seeing the Sagittarius Arm? I've tried to figure this out for myself by looking at various images of the galaxy but haven't found a image/map that I'm sure of. This image was somewhat helpful: http://www.atlasoftheuniverse.com/5000lys.html But it seems like I need to know where some of the stars in the constellation Sagittarius are on a map like this to see the relationship and I haven't found one. Thanks.
