Summary
| Description |
This is the largest conventional refracting telescope in Britain and 7th largest in the world. The lens has a diameter of 28 inches (72cm). Built by Sir Howard Grubb, the first observations were made in 1893 with an eyepiece giving a magnification of 670 times. The 28-inch telescope replaced a smaller refractor by Merz. The same mount was used but the dome was converted from a drum to an onion shape in order to make room for the larger instrument. The dome was originally made of steel and covered with papier mâché. Today the dome has a fibre-glass cover. The design of the mount and dome enable the telescope to be moved to view almost any part of the sky. The recent addition of a computer-aided guidance system makes it easier to use. |
