Milky Way and globular clusters

 Some photos from Tuesday (08 Sep) and Thursday (10 Sep).  The Milky Way image was obtained with a Sony A7iii camera and a Laowa 15mm f/2 lens.  The other images were obtained with an Apertura 60mmED f/6 refractor and an Olympus E-M5iii camera.

 Globular clusters exist in the galactic halo of the Milky Way and are some of the oldest objects in our galaxy.  They are spherical, gravitationally stable clusters of stars with hundreds of thousands or even millions of members.

The globular-cluster images are 1-deg square field-of-view.
