Haynes observed the lunar eclipse of 11 February 1682 from Basing Lane in London, an event also observed by Edmond Halley and John Flamsteed, at Greenwich. He was elected a Fellow of the Royal Society on 2 May 1683, nominated by Flamsteed and Halley.[2][1][3]
A nonconformist, Haynes was in the congregation of Edmund Calamy the Younger, who died at his house in Totteridge, then in Hertfordshire[4] A later published observation from Totteridge noted its distance from London and displacement to the west.[5]
