I have been thinking about something since this image was the Astronomy Picture of the Day, and that is how large and impressive-looking the Carina Nebula is, yet how lacking it is in compact, rich, massive star clusters.

The most compact bright cluster in the Carina Nebula is NGC 3293, and that cluster is even outside the really bright part of the Carina Nebula. By contrast, Trumpler 14, the most compact young cluster in the central part of the Carina Nebula, looks quite poor.
In
this large, 1.4 MB image, you can see NGC 3293 at upper left, and the whole Carina Nebula complex at center. NGC 3293 is very obvious in this image, but Trumpler 14, located in the brightest part of the nebula just below the long broad dust lane running diagonally from upper left to lower right, is inconspicuous.
