Messier 70 – Globular Cluster in the Constellation Sagittarius

Globular Cluster Messier 70 (M70 or NGC 6681) is a globular cluster that can be found in the constellation Sagittarius, it is about 29,300 light years away and close to the galactic center. Focus shifted a bit on this one, but I’m still adding it to my Messier list until I can image this again.

Tech Specs: This image is composed of 32 x 15 second images at ISO 3200 with additional dark and bias frames. Meade LX90 12” telescope, Antares Focal Reducer, and Canon 6D camera. Imaging was done on August 30, 2016.

NGC 6819 – An Open Cluster in the Constellation Cygnus

I had some extra time during an observing session in August 2016 and decided to snap a view pictures of this open cluster in Cygnus, designated NGC 6819. I was surprised at how nice it looked just in the sub-frames! This open cluster is about 7,200 lights years away and has a magnitude of 7.3.

NGC 7006 – A Distant Globular Cluster in Delphinus

StarryNightPro listed this globular at magnitude 10.56, I thought it would be a good test for my telescope.

From SpaceTelescope.org, “NGC 7006 resides in the outskirts of the Milky Way. It is about 135 000 light-years away, five times the distance between the Sun and the centre of the galaxy, and it is part of the galactic halo. This roughly spherical region of the Milky Way is made up of dark matter, gas and sparsely distributed stellar clusters.”
