Description
Drawing of Newton's improvements to the reflecting telescope. Henry Oldenburg made this drawing and sent it to Isaac Newton in a letter, asking him to review and correct it before it was sent on to Christian Huygens to secure Newton's priority for the invention. The two small crowns are on a separate piece of paper that has been attached to the larger drawing; they are meant to demonstrate the magnification ability of the telescope.

Object history
At the meeting of the Royal Society on 11 January 1672, ‘Mr. Isaac Newton was elected. [...] Mention was made of Mr. Newton’s improvement of telescopes by contracting them; and that that, which had sent to the Society of that kind to be examined, had been by the king, and considered also by the president, Sir Robert Moray, Sir Paul Neile, Dr. Christopher Wren, and Mr. Hooke at Whitehall; and that they had so good opinion of it, as they concluded, that a description and scheme of it should be sent by the secretary in a letter to Mons. Huygens then at Paris, thereby to secure this contrivance to the author, who had also written a letter to Mr. Oldenburg from Cambridge, dated January 6, 1671/2, altering and enlarging the description of his instrument, which had been sent him for his review, before it should go abroad. This description was read, and ordered to be entered, together with the scheme, in the Register Book’ (Birch, 3:1). Newton’s letter is printed in Birch 3:2-4 without the figure.
