What are some astronomical points of interest within the constellation Draco?

I'm looking for linked articles please. :)


Specifically, information on the comet viewed in China in 1337 by Williams would be greatly appreciated.





Thank you!|||Draco is a constellation in the northern hemisphere. It is famous due to the Thuban. This star (not the brightest in that constellation) was the Pole Star (North Star) 4600 years back. It was the period of Pyramids construction. It is believed that the angle of slant was oriented to this star at that time.





Eltanin, alpha Draco is the brightest star in this constellation.





Aldhibain (Eta Draconis) is one of the most challenging double star. One of them is about five magnitudes lower than the smaller star. The smaller star shining through the glare of the brighter star.





Mu Draconis is another double star, with a separation of nearly 2 arc-seconds with a magnitude however (5.7).





Nu Draconis, which is another double star a separation of about 62 arcseconds.





Mu and Nu stars are very interesting to sky watchers. 6" telescope will show them apart.|||Notable features





Eltanin (Gamma Draconis) is the brightest star in Draco, with an apparent visual magnitude of 2.24 magnitude units.





One of the deep-sky objects in Draco is the Cat's Eye Nebula (NGC 6543), a planetary nebula that is said to look like a blue disc. There are several faint galaxies in Draco, one of which is the lenticular galaxy NGC 5866, sometimes considered to be Messier Object 102. Another is the Draco Dwarf Galaxy, one of the least luminous galaxies with an absolute magnitude of -8.6 and a diameter of only about 3,500 light years, discovered by Albert G. Wilson of Lowell Observatory in 1954.





The star Thuban (伪 Draconis) was the northern pole star around 2700 BC, during the time of the ancient Egyptians. Due to the effects of precession, it will once again be the pole star around the year 21000 AD.|||Speaking of Thuban, if you want to find it, a quick way to to look at the Big Dipper. Almost everybody knows the two outer stars of the bowl point towards Polaris but they might not know the two inner stars of the bowl point to Thuban. Those stars are Phecda and Megrez.
