M 13 Globular Cluster

M13 Globular Cluster
M13 LRGB

I wasn't sure how it would work using an 81mm scope to get a globular cluster. I think it turned out good.

I left the luminance out, and just did RGB, being careful not to saturate any stars in the center of the cluster.

  • 12-inch LX600 telescope
  • SBIG STF-8300EN CCD
  • 20 x 75 seconds R, B
  • 30 x 75 seconds G
  • 2000px x 1418px

M13 Luminance Only

I wanted to see if I could get a little deeper using longer exposures, without saturating all the center stars.
