Dark Zone centre

Hover your mouse over each blue dot for the name of the object, or click on the dot for a detail page. This map was created using the all-sky hydrogen-alpha map produced by Douglas Finkbeiner from data collected by the WHAM, VTSS and SHASSA hydrogen-alpha surveys.

More commentary on the Dark Zone centre objects will go here.

The large bubble on the lower right surrounds the OB association Scutum OB2. Must write more about that.
