There are, additionally, three most important abilities of a telescope that a user should always consider. Most vital of all is not, as many people think, the magnification. It is the light-gathering ability. Most objects in astronomy are very faint or, at the very least, benefit from being made brighter than they appear to the unaided eye. The light-gathering ability of a telescope depends on the diameter of its primary mirror or lens, which is often called its aperture. All other things being equal, the more aperture you can get for your money, the better the telescope.
Standard time in mid-November, Rigel and Betelgeuse rise in the east, the three-star Belt is vertical between them, and at last one of astronomy’s most awesome moments comes: we see the entirety of Orion’s giant form tilted up above the horizon.

The other is winter’s great star Betelgeuse, which is even brighter than Antares. Like Betelgeuse, Antares is an enormous sun of the type called a red giant, and it varies in brightness (though less markedly than Betelgeuse does). The slightly ruddy hue of Antares is appropriate because it marks the heart of Scorpius, the Scorpion—summer’s brightest and most striking constellation. The only problem with Scorpius and Antares, for many of us, is their southerliness and therefore lowness in the sky.
