Street Telescope Exhibitor
“It must be about eight years since I first exhibited the telescope. I have three telescopes now, and their powers vary from about 36 to 300. The instruments of the higher power are seldom used in the streets, because the velocity of the planets is so great that they almost escape the eye before it can fix it. The opening is so very small, that though I can pass my eye on a star in a minute, an ordinary observer would have the orb pass away before he could accustom his eye to the instrument. High power is all very well for separating stars, and so forth; but I’m like Dr. Kitchener, I prefer a low power for street purposes. A street-passer likes to see plenty of margin round a star. If it fills up the opening he don’t like it.
