June / July Starmap

The starmap for June and July is here: MCAO June / July Starmap.

I create these maps using the wonderful website and Stellarium software. (Stellarium is a free planetarium software program. If you'd like to know what's up in the sky, I highly recommend it!)

Observing Log for 2 June 2017

Skies were clear and beautiful last night! We observed the following objects:

  • Jupiter (planet) : Jupiter was easy to find between the Moon and the bright star Spica. It will be even closer to the Moon tonight (Saturday 3 June). We were able to make out cloud bands on the planet and the four Galilean satellites- Io, Europa, Ganymede, and Callisto.
  • M13, (the Hercules cluster): We also looked at the globular cluster, M13. M13 can be found in the constellation of Hercules and is about 25,000 light-years from Earth.
  • M57 (the Ring Nebula): Next up was M57, a planetary 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 is a particularly beautiful example.
  • M3 (globular cluster) : We also looked at a second globular cluster, M3. This cluster can be found in the constellation Canes Venatici (the hunting dogs), and is about 33,900 light-years from Earth.
  • Mizar (double star) : With the smaller telescope, we split the double star Mizar in the constellation Ursa Major.
  • ε Lyrae (double star) : We also looked at the "double double" star in the constellation Lyra.

Thank you everyone for attending the event last night, and for your interest in the Montgomery College Observatory.
