Quote: Hello Phil,I quite frequently observe NGC 188 through my 10x50 under rural skies as a subtle but obvious glow framed from one side by the arc of several faint stars (8mag).GreetingsMarcin

Quote:If there's one thing at which the constellation of Cepheus excells, it's rich star fields; but there's not much bright & famous to look at when it comes to DSO. So when last night proved very clear (NELM ca +5.5), I put out my Swift 20x80s on their tripod to hunt down some faint stuff. I started out with NGC 188, an open cluster just a few degrees from Polaris. In the 20x80s I could detect something was there, a very faint glow with a scattering of extremely faint stars. If I had just been sweeping this region, I would never have noticed it. Literature shows the brightest stars are mag +12.1, so I was pretty impressed to see any at all. There's supposed to be 150 stars down to mag 18, but these are of course out of reach of my 20x80s. A nice bonus close to NGC 188 is a beautiful double star with two clear white stars of about equal brightness. It's a fairly wide pair but really stands out nicely. Uranometria plots the 9th mag double star just under a degree south of the cluster.

Quote: While Polaris is currently the pole star, the 26,000-year wobble of Earth's axis, called precession, causes the Celestial Pole's aim to trace a 47° circle in the sky. For instance, during the building of the pyramids nearly 4,600 years ago, the North Pole was aimed toward the star Thuban in Draco. Fast forward 5,200 years from now and the pole will be point near Alderamin in Cepheus.
