Telescopes and other instruments by Thomas and Howard Grubb

This list is intended to be as comprehensive as possible for the Grubbs' larger telescopes. The reference lists are representative rather than complete. VTM denotes Glass, I.S., 1997.

48 - in reflector, Melbourne, Australia, 1869.
A reconstruction of the telescope using some of the original parts and a new glass mirror was used for the very successful MACHO project from the late 20th century onwards. Unfortunately it was destroyed in the Mt Stromlo fire of 2003. However, the heavy original parts were not much damaged and a project is now under way in Melbourne to reconstruct the instrument in its original form.

Originally a With mirror on a mounting by Cooke (probably the original mount of Roberts's 7 -in Cooke refractor which became the guide telescope of his 20 - in photographic reflector), this telescope was renovated by Grubb for presentation to Trinity College Dublin (Dunsink Observatory) in 1888. Later it was remounted by Grubb. Mounting later carried a 28-inch reflector.

15 - in refr, Dunn's Observatory, Maidenhead, England
There was a f/12 visual refr. of 1893 and a photographic one of 1894. The latter telescope is the ``portrait lens" of 15 inches aperture and 89 inches focal length referred to in Observatory (1897). Grubb also supplied a hand-operated rising floor. Later at Wilfrid Hall's observatory in Hepple Woodside, Northumberland. A photograph exists in the album ``Miscellaneous Telescopes", Tyne and Wear Archives (Grubb-Parsons collection). Now known as the Wilfrid Hall telescope and located at the Alston Observatory of the University of Central Lancashire. Owned by the Royal Astronomical Society.

Parts and a mount for a 12-inch speculum-metal reflector were sent to Melbourne so that local astronomers could practice polishing techniques for the 48-in reflector (see chap. 2). History uncertain, but at least mirror may still exist (Orchiston, 1990, private communication).

Notes:
Besides telescopes and domes, the Grubbs constructed many other instruments. Astronomical accessories included chronographs (a means for noting the precise time at which an event occurred), eyepiece micrometers (devices for measuring small angular distances such as the separation and position angle of double stars), spectroscopes, and clocks.


A 6-prism spectrograph made for Huggins is in the Whipple Museum of the History of Science, Cambridge (Burnett and Morrison-Low, (1989).


A 6-prism spectrograph of a different pattern to the above is in the National Museum of American History, Smithsonian, Washington. It was used by C.A. Young at Princeton.


The Royal Dublin Society possesses a 3-prism laboratory spectroscope.


Miscellaneous instruments,
other than the magnetic equipment mentioned in Chap. 1 of VTM, included base-line measures for surveying, microscopes, photographic lenses and a special heavy-duty precision balance from Thomas Grubb's time, now in the chemistry department of Trinity College, Dublin. The Museum of the History of Science in Oxford has a Thomas Grubb microscope.
