This Dollond Day or Nigh telescope was designed to be used in any light conditions, as its name implies. Telescopes are optical instruments designed to make objects appear to be larger or closer. The discovery of the first telescope in 1608 can be attributed to Hans Lippershey of the Netherlands when he discovers that holding two lenses up some distance apart bring objects closer. He applies for a patent on his invention and this becomes the first documented creation of a telescope. Then in 1668, Newton produces the first successful reflecting telescope using a two-inch diameter concave spherical mirror. This opened the door to magnifying objects millions of times far beyond what could ever be obtained with a lens. It wasn’t until 1729 that Chester Moor Hall develops an achromatic lens (two pieces of glass with different indices of light refraction combined produce a lens that can focus colours to almost an exact point resulting in much sharper images but still with some distortion around the edges of the image. Then in 1729 Scottish instrument maker James Short invents the first parabolic and elliptic, distortion-less mirror ideal for reflecting telescopes. We now come to John Dollond who improves upon the achromatic objective lens by placing a concave flint glass lens between two convex crown glass lenses. This had the effect of improving the image considerably. Makers Information: John Dollond (1707-1761) London England he was a maker of optical and astronomical instruments who developed an achromatic (non-colour distorting) refracting telescope and practical heliometer. A telescope that used a divided lens to measure the Sun’s diameter and the angles between celestial bodies. The son of a Huguenot refugees Dollond learned the family trade of silk weaving. He became proficient in optics and astronomy and in 1752 his eldest son, Peter joined his father in an optical business, in 1753 he introduced the heliometer. In the same year, he also took out a patent on his new lenses. He was elected a fellow of the Royal Society in May 1761 but died suddenly in November and his share in the patent passed to his son Peter. In subsequent squabbles between Peter and the many London opticians who challenged his patent, Peter’s consistent position was that, whatever precedents there may have been to his achromatic lenses, his father had independently reached his practical technique on the basis of his theoretical command of Newtonian optics. As a result of maintaining his fathers patent, Dollond s became the leading manufacturer of optical instruments. For a time in the eighteenth and nineteenth century the word 'Dollond' was almost a generic term for telescope rather like 'Hoover; is to vacuum cleaner. Genuine Dollond telescopes were considered to be amongst the best. Peter Dollond (1731-1820) was the business brain behind the company which he founded in Vine Street, Spitalfields in 1750 and in 1752 moved the business to the Strand London. The Dollonds seem to have made both types of telescopes (reflecting and refracting), possessing the technology to produce significant numbers of lenses free of chromatic aberration for refracting telescopes. A Dollond telescope sailed with Captain Cook in 1769 on his voyage to observe the Transit of Venus. Thomas Jefferson and Admiral Lord Nelson were also customers of the Dollonds. Dollond & Co merged with Aitchison & Co in 1927 to form Dollond & Aitchison, the well-known high street chain of opticians, now fully part of Boots Opticians. They no longer manufacture but are exclusively a retail operation.    John Dollond's experiments in optics and how different combinations of lenses refract light and colour gave a better understanding of the divergent properties of lenses. That went on to inform and pave the way for the improvement of our understanding of optics that is represented today. Dollond was referred to in his time as the "Father of practical optics" as a leader in his field he received many prestigious awards. The telescope in the collection is a good example of one of Dollond's early library telescopes. Its connection with one of England's 18th century pioneers in optical development makes it a significant and an important item to have within the collection.Telescope: Dollond's Telescope, Day or Night model navigational instrument.

The first voyage of Lieutenant James Cook was a combined Royal Navy and Royal Society expedition to the south Pacific Ocean aboard HMS Endeavour, from 1768 to 1771. The aims of this first expedition were to observe the transit of Venus across the Sun (3–4 of June 1769). Departing from Plymouth in August 1768, the expedition crossed the Atlantic, rounded Cape Horn and reached Tahiti in time to observe the transit of Venus. In September 1769 the expedition reached New Zealand. In April 1770 they became the first known Europeans to reach the east coast of Australia, making landfall near present-day Point Hicks, and then proceeding north to Botany Bay. The expedition continued northward along the Australian coastline. In October 1770 they reached the port of Batavia in the Dutch East Indies. They resumed their journey on 26 December, rounded the Cape of Good Hope on 13 March 1771, and reached the English port of Deal on 12 July. The voyage lasted almost three years. Voyage 1 (1768–1771): ship Endeavour Route: London – Madiera – Rio de Janeiro – Cape Horn – Tuamotu Island – Tahiti – Society Islands – New Zealand – New Holland (Australia) – East Timor – Java – Batavia – Cape of Good Hope – St Helena – Ascension – LondonCook joined the British merchant navy as a teenager and joined the Royal Navy in 1755.Colour reproduction of portrait of Captain Cook by Nathaniel Dance (1735-1811)Captain James Cook - The First Voyage 1768-1771captain james cook, nathaniel dance (1735-1811), endeavour, navigators, sea voyage

Original Ships History: Aréthuse was a French frigate, launched in 1757 during the Seven Years War between England and France. She was captured by the Royal Navy in 1759 and became the fifth-rate HMS Arethusa. She remained in Royal Navy service for twenty years until she was wrecked after being badly damaged in battle. The ship was constructed at Le Havre for privateer warfare as ”Pélerine” and soon after her launch, she was purchased by King Louis XV (1710-1774) and commissioned as Aréthuse on 21 January 1758. In June, under captain Vauquelin, she sailed through the British blockade of Louisbourg helping to defend the site before departing, again forcing the blockade. On 18 May 1759, she was in transit from Rochefort to Brest, under the command of Louis-Philippe de Rigaud, Marquis of Vaudreuil, when she was intercepted near Audierne Bay (Baie d'Audierne) by three Royal Navy ships the Thames, Venus and Chatham. She attempted to escape but after two hours, lost her topmasts and was overtaken by her pursuers. Thames and Venus engaged her with heavy fire, causing 60 casualties before the vessel surrendered. She entered service with the Royal Navy for the rest of the war, and was in service in British home waters and became responsible for the capture of several French privateer cutters. In 1777, a Scotsman James Aitken, widely known as John the Painter, was hanged from her mizzenmast for burning the Rope House at Portsmouth Royal Dockyard on 7 December 1776, to aid the struggle of American independence. The mast was struck from the ship and re-erected at the dockyard entrance so as many people as possible could watch the execution. On 17 June 1778, she fought a famous duel against the French 36-gun frigate, Belle Poule. Belle Poule was on a reconnaissance mission, along with the 26-gun Licorne, the corvette Hirondelle and the smaller Coureur when she encountered a large British squadron that included Arethusa at a point 37 km south of The Lizard. Admiral Keppel, commanding the British fleet ordered that the French ships be pursued. The captain of Belle Poule refused the order to sail back to the British fleet. The British fired a warning shot across his ship's bow, to which he responded with a full broadside. This action began a furious, two-hour battle between the two ships that resulted in the deaths of the French second captain and 30 of the crew. However, Arethusa was crippled by the loss of a mast and withdrew, allowing Belle Poule to escape. This battle was the first between British and French naval forces during the American Revolutionary War and took place around three weeks before France had made a formal declaration of war. The battle was widely celebrated in France as a victory, even inspiring a hair-style in court circles that included a model of Belle Poule. It was also viewed as a victory in Britain and became the subject of a traditional Sea shanty, The Saucy Arethusa. On 18 March 1779, under captain Charles Holmes Everitt, Arethusa engaged the French Aigrette, under Lieutenant Mortemart, sustaining considerable damage in the fight. Arethusa was wrecked the next day off Ushant, It was the fame of this Arethusa which induced the Royal Navy, during the following two centuries, to bestow the name on a further seven consecutive individual ships and two consecutive classes of cruisers.
