Browning Reflecting Telescope

<< >>
Description
The introduction of silvered-glass mirrors—easier to figure and more durable than solid metal ones—made reflecting telescopes popular, especially with amateur astronomers.
This example is marked "John Browing London." It has a simple alt-azimuth mount. The aperture is 4.25 inches; the tube is 38.5 inches long.
John Browning was a young instrument maker when he issued A Plea for Reflectors, Being a Description of the New Astronomical Telescopes with Silvered-Glass Specula (London, 1867). He offered telescopes with mirrors made by the retired schoolteacher, George Henry With.
