The components are 5" apart, the colours pale white and violet.

With the full powers of a 3-1/2-inch glass a faint companion may be seen above [lambda].
The star [zeta], the lowest in the belt, may be tried with a 3-1/2-inch glass.

It is a close double, the components being nearly equal, and about 2-1/2" apart (see Plate 3).
For a change we will now try our telescope on a nebula, selecting the great nebula in the Sword.

The place of this object is indicated in Plate 2.

There can be no difficulty in finding it since it is clearly visible to the naked eye on a moonless night--the only sort of night on which an observer would care to look at nebulae.
