Beginning with Crater, let us look first at alpha, a yellow fourth-magnitude star, near which is a celebrated red variable R. With a low power we can see both alpha and R in the same field of view, like a very wide double. There is a third star of ninth magnitude, and bluish in color, near R on the side toward alpha. R is variable both in color and light.
The star 30 is a very pretty double, magnitudes six and seven, distance 38.6", p. 273°. Sigma 289 consists of a topaz star combined with a sapphire, magnitudes six and nine, distance 28.5", p. 0°. The fourth-magnitude star 41 has several faint companions.
Still retaining the five-inch in use, we may next turn to the other end of the Belt, where, just under zeta, we perceive the fourth-magnitude star sigma. He must be a person of indifferent mind who, after looking with unassisted eyes at the modest glimmering of this little star, can see it as the telescope reveals it without a thrill of wonder and a cry of pleasure.
Like Sirius, Vega displays the lines of hydrogen most conspicuously, and it is probably a much hotter as well as a much more voluminous body than the sun. Close by, toward the east, two fourth-magnitude stars form a little triangle with Vega. Both are interesting objects for the telescope, and the northern one, epsilon, has few rivals in this respect. Let us first look at it with an opera glass.
By a hasty calculation with the aid of this invention, Phobar found that the new star was about three thousand light-years distant, and that it was hurtling backward into space at the rate of twelve hundred miles per second. The remarkable feature of his discovery was this appearance of a fourth-magnitude star where none had been known to exist. Perhaps it had come into existence this very night.
The other fourth-magnitude star near Vega is zeta, a wide double, magnitudes fourth and sixth, distance 44", p. 150°. Below we find beta, another very interesting star, since it is both a multiple and an eccentric variable.
Then, in this case at any rate there was the very finicky task of picking out a fourth-magnitude star of whose planets one was his destination. He aimed for it with ultra-fine precision. "Overdrive coming," he said presently. "Hold on!" Space reeled. There was nausea and giddiness and a horrible sensation of falling in a wildly unlikely spiral.

Burnham has doubled the fourth-magnitude star, distance 0.23". The second group of four stars consists of three of the eighth to ninth magnitude, arranged in a minute triangle with a much fainter star near them. Between the two quadruple sets careful gazing reveals two other very faint stars.
