John Herschel produced this pencil drawing of the nebulosity in the Eta Argus region of the southern sky on April 15, 1836 using his 6.4-m focal length reflector at Feldhausen, Cape Town, South Africa. Notice how a triangular skeleton of field stars are used to help position the nebulosity. (Monograph on Argus, John Herschel Papers, RAS: JH 3/1.8, p.10)
