M7 Open Cluster in Scorpius
with 8" f/3.9 Astrograph in Happy Jack
Uploaded 7/16/16

This is an amazing field, very close to the very center of our Galaxy. The ultra rich star field, and other tiny deep sky objects in the same field make for a very tempting target during the summer. Dust obscuration is high in this part of the sky, and nearly all stars are both dimmed and color shifted into the yellow range. For this image, I removed most of the dark brown dust obscuration in processing to reveal the beautiful blue sapphires laying on a velvet background of countless distant suns. Two images are provided here, the first is the full image with no annotations, and the second Ive labeled the globular cluster on the right, and three of the blue/red planetary nebulas that dot the field. See also a nice well defined dark nebula to the clusters upper left.
