Really massive and luminous Star Clusters are exciting objects;
pity that NGC 3603, Westerlund 1 and Westerlund 2 are greatly dimmed by many magnitudes of dust extinction!
I just came upon this fantastic map that shows where the so-far discovered Very Massive
young clusters are in our galaxy!(known clusters of at least 10,000 solar masses)
(note that the distance of Westerlund 2 is not settled as yet)
I suspect that it is quite possible to visually detect some "super star clusters" in other galaxies, though it would be a great challenge. The most massive of these clusters can be three or four magnitudes more luminous than Omega Centauri.
