Cosmography archives On Two Distribution Maps of the Nebulæ and Clusters in Dr. Dreyer's Catalogue of 1888. by Sidney Waters (1894) ui.adsabs.harvard.edu/abs/1894MNRA... 🔭🧪 @rasjournals.bsky.social

The nebulæ and clusters of the Northern Heavens drawn upon an equal surface projection. The chart features a drawing of the Milky Way. The irresolvable nebulæ, now understood to be galaxies, are marked as black dots. Their distribution is rather inhomogeneous, exhibiting structures such as aggregations and filaments. The resolvable nebulæ are marked as red dots. Star clusters are marked with a red cross; they mostly adhere to the track of the Milky Way.

The nebulæ and clusters of the Southern Heavens drawn upon an equal surface projection. The chart features a drawing of the Milky Way. The irresolvable nebulæ, now understood to be galaxies, are marked as black dots. Their distribution is rather inhomogeneous, exhibiting structures such as aggregations and filaments. The Large and Small Magellanic Clouds stand out as extraordinary aggregations near the centre of the chart. The resolvable nebulæ are marked as red dots. Star clusters are marked with a red cross; they mostly adhere to the track of the Milky Way.
