NGC 6335. JH says of this, "The whole lower end of the zone is strongly affected with nebulous patches," and gives only an approximate position for it. Though included in Cederblad's catalogue of bright diffuse nebulae, there is no bright nebulosity in the area. Instead, the Southern Sky Survey films show a patchy field of star clouds, defined by the dust of dark nebulae. It is apparently these star clouds that JH saw in the spring of 1837, giving him the impression of patchy nebulosity all through his field. (Three years earlier, he happened on the same field, giving a position then about 5 minutes east; this has become NGC 6360, which see.)
I've adopted the approximate center of the brightest patch of stars nearest JH's position as the position for NGC 6335. This is about a minute west of his place which lands in a relatively poor field -- in other words, in the midst of a dust cloud.
Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "the whole lower end of the zone is strongly affected with nebulous patches."
Bailey, examining a Bruce plate (Harvard Annals, Vol 72, No 2), describes it as "Milky Way, rich in stars, no nebulosity seen."
