Observing Log for Friday 16 August 2019

Well, we're two for two! The clouds moved off and we had a clear, but humid evening. The observing log is below. The sky doesn't change that much over two weeks, so it's about identical to the last one. :)

  • Jupiter
  • Saturn
  • Albireo: Albireo is a double star system in Cygnus. The two stars (one blue, one gold) can't be resolved with the naked eye, but through our telescopes we are able to see the pair. The system is about 430 light-years distant.
  • M13 (the Hercules cluster): M13 can be found in the constellation of Hercules and is about 22,000 light-years from Earth. There are about 150-160 globular clusters located in the halo of our galaxy. These clusters contain some of the oldest stars in the Milky Way.
  • M57 (the Ring Nebula): M57 can be found in the constellation of Lyra and is located about 2,300 light-years from Earth. Planetary nebulae are the remnants of lower mass stars after they've used up their nuclear fuel. The Ring Nebula appeared as a delicate smoke-ring in the eyepiece.

Thanks to Iadviga for assistance with the event, and for getting us to try some cell phone astrophotography.

And as always, thanks to everyone for attending!
