No notable object visible at the coordinates (20h6.8' 38°21') in a rich galactic starfield, verified star field with chart.

Archinal & Hynes equate Basel 6 with NGC 6874 just preceeding the coordinates for Basel 6. I will be adopting this equivalency based on this and a negative observation at the listed coordinates.

WH found this on 15 Sept 1792, describing it as "A coarsly scattered cluster of large stars, of a right-angled triangular shape." This is exactly the configuration seen about 15 seconds preceding the NGC position (from John Herschel), and is the cluster that I've taken as the NGC object. The tabulated position refers to the approximate center of the triangle.

John Herschel's position, copied correctly into GC and NGC, refers to the 10th magnitude star at one apex of the triangle, east of the center.
