Eta Carinae is shown as a star of the second magnitude. Interesting because it started to brightene in 1837, to become one of the brightest star in the sky in March 1943.
An interesting article about this can be foud at https://academic.oup.com/mnras/article/415/3/2009/1043616.
It suggests the star should have been of the first magnitude around 1850.
Also interesting is the presence of the eta Carinae nebula, just below the star.
It is missing in Duncan Bradford's 'The Wonders of the Heavens' (1837), where an earlier version of the maps is used.
