Neptune Discovery Telescope
The telescope at New Berlin Observatory (1835–1913), that discovered Neptune, was an achromatic refractor of 9 Paris inch (9.6 English inches or 24.4 cm) aperture made by the late Joseph Fraunhofer's firm, Merz und Mahler. It was a high performance telescope of its era, with one of the largest achromatic doublets available and a finely made equatorial mount, with a clockwork drive to move the 4 m (13.4′) main tube in time with Earth's rotation. Eventually the telescope was moved to Deutsches Museum in München, Germany, where it can still be seen in the 21st century as an exhibit.

Famous quotes containing the words neptune, discovery and/or telescope:
“But we are spirits of another sort.
I with the morning’s love have oft made sport,
And like a forester the groves may tread
Even till the eastern gate, all fiery-red,
Opening on Neptune with fair blessèd beams,
Turns unto yellow gold his salt green streams.”
—William Shakespeare (1564–1616)
“The new supplants the old. Yet men’s minds are stuffed with outworn bunk. Educating the young in the latest findings of authorities and scholars in the social sciences is important. It is equally important to devise ways and means for aiding the middle-aged and old to reexamine hang-over unscientific doctrines and ideas in the light of recent discovery and research.”
—Mary Barnett Gilson (1877–?)
“The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow, outvalues all the theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.”
—Ralph Waldo Emerson (1803–1882)
