Clusters are seen in several forms, Open where the associated stars are spread out, Tight is it sounds a group of stars near each other, and Globular a "ball" of stars often looking like a Christmas Tree ornament, they can have hundreds of thousands of stars in the globular.

This is M45 a open cluster that has nebulosity associated with it. It is visible to the naked eye looking like a little dipper.The thin line is a satellite.

What the other guy said: terrific!
 
NGC 869 the double cluster also listed as Caldwell 14

From Wikipedia
The Double Cluster (also known as Caldwell 14) consists of the open clustersNGC 869 and NGC 884 (often designated h Persei and χ (chi) Persei, respectively), which are close together in the constellation Perseus. Both visible with the naked eye, NGC 869 and NGC 884 lie at a distance of about 7,500 light years in the Perseus Arm of the Milky Waygalaxy

from the wiki
Omega Centauri (ω Cen, NGC 5139, or Caldwell 80) is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 17,090 light-years (5,240 parsecs), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years.<a href="https://en.wikipedia.org/wiki/Omega_Centauri#cite_note-10"><span>[</span>10<span>]</span></a> It is estimated to contain approximately 10 million stars, with a total mass of 4 million solar masses,<a href="https://en.wikipedia.org/wiki/Omega_Centauri#cite_note-11"><span>[</span>11<span>]</span></a> making it the most massive known globular cluster in the Milky Way.

Omega Centauri is very different from most other galactic globular clusters to the extent that it is thought to have originated as the core remnant of a disrupted dwarf galaxy
