Dear all,

This is the observing log for the star party on Sep 22, Friday.
Please read on, but for the impatient: https://youtu.be/4Ux06MfnGI4

Conditions started as clear skies, warm temperature, low humidity.
Observing started at around 19:45 from Broadmead. We set up the 11"
diameter Celestron telescope and the 4" diameter Vixen telescope. 

We oriented the Celestron using bright stars, after which the computer
of the telescope knew the orientation of the telescope, and could slew
to any object selected via the hand controller. 

Saturn: Through the Celestron we saw Saturn and its ring system. We saw
the moons Titan, Iapetus, and another 3 moons (Rhea, Thetys, Dione). 
We were unsure about seeing Mimas or Enceladus, which probably require
a larger aperture telescope.  Saturn set very early, so we had to give
up observing around 20:15.  We also observed it through the small Vixen
telescope, through which it appeared as an elongated planet, the rings
barely discernible.

We went through the circumpolar constellations: Ursa Major, Ursa Minor
(Polaris being the north polar star), Draco, Cepheus, Cassiopeia.  We
reviewed the summer and fall constellations, such as Cygnus (with
Deneb), Lyra (with Vega) and Aquila (with Altair).  Fall
constellations: Pegasus, Andromeda, Perseus. 

We observed Uranus, and saw some of its faint moons. We also observed
Neptune, and noted its bluish color. 

We observed a number of binary stars and "deep sky objects", such as:

 * Alcor-Mizar: https://en.wikipedia.org/wiki/Mizar_and_Alcor

 * Albireo: https://en.wikipedia.org/wiki/Albireo

 * The Ring Nebula: https://en.wikipedia.org/wiki/Ring_Nebula

 * The Dumbbell Nebula: https://en.wikipedia.org/wiki/Dumbbell_Nebula

 * Grand globular cluster M13: https://en.wikipedia.org/wiki/Messier_13

 * Another globular cluster, just setting behind the trees, while
   chasing holes between the clouds: https://en.wikipedia.org/wiki/Messier_3

 * Andromeda Galaxy (highly recommended for observing groups!):
   https://en.wikipedia.org/wiki/Andromeda_Galaxy

 * Twin clusters: https://en.wikipedia.org/wiki/Double_Cluster

If I missed something, please report!

We also tried out a couple of filters that either reduce light
pollution, or enhance the OIII lines of planetary nebulae. 

The sky become overcast for about one hour, which gave a good
opportunity for the weak and tired students to sneak away.  As usual,
once most folks were gone, sky cleared up again, and remained very
clear till the morning.  We wrapped up things at 23:30.  Altogether,
was a very productive star party.  Thanks for all of you joining!
