M71 in Sagitta Orion 8" f/4 Astrograph

Uploaded 10/7/16

 There are areas of the Milky Way that are so dense in stars that deep images of those regions show apparently more stars than sky in between! The field around this rich open cluster M71 is such a field. Easily seen in binoculars as a faint misty patch in the Arrow constellation, zooming in reveals a rich assemblage of multi hued stars, with little gaps between them. While there are no galaxies visible in the background here, spend some time with the larger image and see all the spectral types you can see. The cluster itself is a yellow and blue rich cluster, and there seems no definite edge to its realm.

From a technical point of view, the Baader coma corrector is working great here, pinpoints right to the edges with a f/3.9 parabolic mirror.
