A summary of these methods: 1  Cepheid variable stars and their cousins the RR Lyrae stars are the primary distance indicators in the galaxy and the local group. 2  They pulsate radially (basically at the sound speed in the envelope of the star) with a period inversely proportional to the square root of the density.
One more example with the Big Dipper is to use 2 of its stars to point to a beautiful pair of galaxies, M81 & M82. Again, don't expect to see any structure but what you will find are 2 lovely galaxies that fit in one lower power field of view.
