Its colour is a bluish-white.

In an ordinary telescope Vega appears as a single star, but with a large object-glass two distant small companions are seen.

A nine-inch glass shows also two small companions within a few seconds of Vega.

In the great Harvard refractor Vega is seen with no less than thirty-five companions.

I imagine that all these stars, and others which can be seen in neighbouring fields, indicate the association of Vega with the neighbouring stream of the Milky Way.
Let our observer now direct his telescope to the star [epsilon] Lyrae.
