Most amateur astronomers use portable telescopes, and it is imperative that if you have one of these you correctly align the polar axis so that it points towards the NCP. Different telescope manufacturers recommend different methods of doing this. Most involve at least a degree of trial and error (Fig. 1). For short-term visual observing, it is perfectly acceptable to try to align the axis on Polaris, the Pole Star. In most cases this suffices to track an object; however, after a few hours it will be necessary to realign the telescope.
In addition there are rare and hot stars called Wolf-Rayet stars, class WC and WN, exploding stars Q, and peculiar stars, P. Furthermore, the spectral types themselves are divided into ten spectral classes beginning with 0, 1, 2, 3 and so on up to 9. A class A1 star is thus hotter than a class A8 star, which in turn is hotter than a class F0 star. Further prefixes and suffixes can be used to illustrate additional features: A star with emission lines (also called f in some O-type stars) Metallic lines A peculiar spectrum A variable spectrum A star with a blue or red shift in the line (for example P-Cygni stars) e m p v q And so forth.
Karkoschka; this book is, incidentally, a perfect companion to this volume. Various other star atlases are available30 that show objects down to much fainter magnitudes and should be in the library of any serious observer. A recent addition to the amateur astronomer’s arsenal is the planetarium, or computerized star atlas. There are numerous computer programs that will plot a virtual night sky, for whatever time and location you desire. They range in sophistication from very simple “star atlas” types, showing just the basic constellations and objects contained therein, to the more detailed “ephemeris” type, which have stars and other celestial objects such as galaxies and nebulae, often down to a magnitude of 12 and even fainter.
