Good shooting there Aubrey.

I shot this back in August at my Observatory at Meyer's as I was checking polar alignment. This is an interesting Globular.

It is very low in the Galactic plane and is affected by Galaxy extinction effects of the Milky Way. I am told that the stars that show orange are mostly blue if you correct for the light shift. It is about 13K light years away. The blue stars that you see are foreground stars.

M71,until the 1970's, was thought to be an open cluster but later was proven to be a loosely packed Globular cluster.

I have also read that Hubble has imaged Galaxies through the stars of this Globular. I can not find any data on this but I think I can see a couple of Galaxies in this image at 400X. I can not be sure at this time and will need more research.
