Dark clouds of Aquila

Aquila – LDN 673 and Friends

September 17th, 2017

I took this data from Bortle 0 skies outside of Ft. Davis TX and from semi-dark skies in Granbury, TX. While the milky way star cloud is quite bright, the details in the dark nebulae are very hard to isolate without dark skies.

Object details:

LDN 673 (the dark mass in the center right) is one of many dark nebulae in Aquila, the constellation of the eagle. These dark clouds are condensing due to gravity and will slowly form stars. This frame is just west of Altair, one of the bright stars of the summer triangle. The endless mass of bright stars on the left is an un-obstructed view at our milky way galaxy.
