History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 6480 is a star cloud in the Milky Way closely matching JH's sketch in the CGH Observations. My estimated position for the center of the projection to the east is about 10 seconds of time west of JH's, but there is no doubt of the identity.

Historical observations

John Herschel (1847) Cape Observations

Two un-numbered entries are inserted between h3713 and h3714 in the Cape Catalogue.

The first reads:

RA (1830.0) 17 43 40.9, NPD 120 23 22

"An extraordinary B nebulous portion of the milky way, on a black ground v L; an angle taken where there is a * 12m. [See fig. 2, Pl. V., copied from a diagram made at the time, which represents this remarkable and instructive object as marked by a well defined contour.]"

Sweep 794 [1837 June?]

The second entry reads:

RA (1830.0) 17 44 28.8 NPD 120 19 37

"The milky way here is so sharply terminated, that the southern half of the field has few stars, while the northern is so full as to be almost nebulous."

Sweep 478 [1834 August 03]

In the image below (Plate 5, Fig 2), south is at the top and west is to the right.

The montage below compares a photograph (by Dieter Willasch) of the region with Herschel's sketch.

NGC/IC Dreyer (1888, 1895, 1908)

The NGC (1888) lists the number 3713 in John Herschel's catalogue for both NGC 6480 and NGC 6483. The description in the Cape Observations for No. 3713 corresponds with the description recorded for NGC 6483.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF S.
