Description:The inch refractor was fabricated at the same time, and one of the two original domes was built specifically for this telescope. Located in the larger dome of the main observatory building, the Great Lick refractor is 57 feet long, 4 feet in diameter, and weighs over 25, lbs. The photo on the left shows the cleaning of these lenses, a delicate maintenance procedure that few are allowed to witness. In this procedure, the end of the telescope that is usually pointed towards the sky must be brought down to the dome floor by repositioning the counterbalances that hold the telescope in its working position. This repositioning must be done carefully due to the mass of the telescope and the fragility of the glass. The two inch diameter glass disks were fabricated in France, and ground and polished into lenses in Massachussetts by Alvan Clark and his son Alvan G.
