M13 - The Great Globular Cluster in Hercules

My Latest Shot of M13, The Great Globular Cluster in Hercules

A little over a month ago, I posted one of my images of Messier 13, the great globular cluster in Hercules that I got one night through my telescope.  Well, thanks to a clear night last week and more astrophotography experience, I managed to get a far better shot.  I still have a lot to learn about astrophotography and some equipment upgrades to make to get even better pictures (I just ordered a polar scope for my setup right before I started writing this post so that should help with my images starting on Saturday when it arrives) but I am really exited with my progress so far.  When you compare last month’s shot to this one, there is a HUGE difference!  I love that you can now see the colors of the different stars too!

Here is a little bit of a description of what you see in the picture above followed by the details of the setup and the shot for those curious to know what I used to take this shot and how I took it.

Messier 13 (M13) is about 145 light-years in diameter, and it is composed of several hundred thousand stars. M13 is 25,100 light-years away from Earth and was discovered by Edmond Halley in 1714, and catalogued by Charles Messier on June 1, 1764.
