Star Cluster
A Star Cluster or star cloud is a group of stars. There are two types of star clusters: Globular Clusters and Open Clusters.
A Globular Cluster is a tight group of hundreds or thousands of very old stars, which are gravitationally bound.
An Open Cluster is a more loosely clustered groups of stars, generally contain fewer than a few hundred members, and are often very young.
There are a variety of star clusters in Elite: Dangerous that contain rich survey data opportunities.

Trumpler 16
Trumpler 16 is the home of WR 25, currently the most luminous star known in our Milky Way galaxy, together with the less luminous but more massive and famous Eta Carinae star system and the O2 supergiant HD 93129A.
Trumpler 16 can be reached by plotting a course to CPD-59 2574.
Eta Carinae can be located by name, using the search tool.
Trumpler 14
Trumpler 14 is about half a million years old and one of the youngest known star clusters in the galaxy. Due to its location within the inner parts of the Carina Nebula, Trumpler 14 is currently undergoing massive star formation. As a result, the star cluster exhibits many stars of late O to early A spectral type, which are very massive (at least 10 solar masses), short-lived and hot (20000 K).
Trumpler 14 can be reached by plotting a course to CPD-57 3518.
A class A blue supergiant can be located near the cluster by plotting a course to HD 91969.
Messier 67
Messier 67 (also known as M67, NGC 2682, or the Cancri Cluster) is an open cluster in the constellation of Cancer.
The cluster had previously been out of reach, due to the 219 light-year gap between OUTOTCH SA-U D4-O and AH CANCRI. However, due to a recent discovery of a massive FSD boost via neutron star, what is known as the "Cancri Climb" became possible. M67 does not contain any neutron stars.
In mid January 2017, a fleet of approximately 360 starships of the Distant Stars Expedition embarked on a treacherous mission to a system dubbed "Elesium," within the M67 Galaxy... never to return. Although, one commander has confirmed a 252.74 light-year jump via engineer upgrades is possible, so any commander can conceivably reach M67 and return.
Messier 67 can be found by searching for NGC 2682 FBC 4778.
NGC 3590
NGC 3590 is a small open cluster of stars located in the constellation of Carina (the Keel) and is roughly 35 million years old.
NGC 3590 can be reached by plotting a route to 2MASS J11130656-6047542.
