Astronomy with an Opera-glass: A Popular Introduction to the Study of the Starry Heavens with the Simplest of Optical Instruments

So intimately was Sirius connected in the minds of the ancient Egyptians
with the annual rising of the Nile, that it was called the Nile-star.
When it appeared in the morning sky, just before sunrise, the season of
the overflowing of the great river was about to begin, and so the
appearance of this star was regarded as foretelling the coming of the
floods. The dog-days got their name from Sirius, as they occur at the
time when that star rises with the sun.
Your eyes will be fairly dazzled when you turn your glass upon this
splendid star. By close attention you will be able to perceive a number
of faint stars, mere points by comparison, in the immediate neighborhood
of Sirius. There are many interesting objects in the constellation. The
star marked Nu ([nu]) in the map is really triple, as the smallest glass
will show. Look next at the star-group 41 M. The cloud of minute stars
of which it is composed can be very well seen with a field-glass or a
powerful opera-glass. The star 22 is of a very ruddy color that
contrasts beautifully with the light of Epsilon ([epsilon]), which can
be seen in the same field of view with an opera-glass. Between the stars
Delta ([delta]) and [omicron]¹ and [omicron] squared there is a remarkable
array of minute stars, as shown in the accompanying cut. One never sees
stars arranged in streams or rows, like these, without an irresistible
impression that the arrangement can not be accidental; that some law
must have been in operation which associated them together in the forms
which we see. Yet, when we reflect that these are all suns, how far do
we seem to be from understanding the meaning of the universe!
