Night Thirteen - Hercules Cluster, M 13

-
I was headed to bed last night and while shutting down the first floor lights, I peeked outside and realized that the skies had cleared. I set up the Dwarf 3 and grabbed these stacked images of the Hercules Cluster, M 13. This was a 30 second exposure with almost 200 images stacked. This star cluster consists of several hundred thousand stars and is located in the constellation Hercules. The stars are so densely packed that at first it was thought to be one solid object. Then in 1779, telescopes became good enough to resolve the cluster into individual stars. The packing is so dense that stars are colliding with each other within the cluster.

The new Dwarf 3 telescope has arrived

 After a 6 month wait the new "smart telescope" has arrived.  There is no eyepiece to view the celestial objects. Instead, the telescope is linked to your phone or tablet for viewing and images are downloaded when you connect the scope to your desktop. Dwarf 3 telescope First night's images: The Andromeda Galaxy This galaxy is approximately 2.5 million light years from Earth.  Thought to be about the same size as the Milky Way Galaxy and it's headed our way. Should arrive in 4 to 5 billion years. Few actual collisions are expected as the stars are so widely distributed with the final result being one much larger galaxy. This is the only object visible to our naked eye that lies outside of the Milky Way. Everything else we see at night, lies within our own galaxy.  Here is the same image as it comes off the telscope with zero processing.  Here is one more image with the number of background stars reduced through processing.

  New objects tonight.  First, the California Nebula. This emission nebula bears a slight resemblence to the shape of the State of California. Next the Pleiades (M45). This is an open star cluster that is the nearest Messier object to the Earth.  Lastly, the Heart Nebula. You can just make out the top of the heart shape in red.
