Description: NGC 1624 is a different little open cluster embedded in a faint nebula that is quite reminiscent of the well known Cocoon nebula. The cluster itself is a tight grouping of only a very few stars.
NGC 1624, also known as Sh2-212 in the Sharpless catalog, is a very young open cluster in the constellation Perseus inside an emission nebula.
The cluster consists of several massive main sequence stars and a large number of pre-main sequence stars. The brightest star is NGC 1624-2 near the center of the cluster. This star is the source of strong X-rays and rotates with a very strong magnetic field. It is potentially an area of massive star formation. According to Robert Trumpler's classification of open clusters, this cluster contains fewer than 50 stars (letter p) with a high concentration (I) and whose magnitudes are distributed over an average interval (number 2). The letter n at the end (I2pn) means that the cluster is inside a nebula.
Along with nearby emission nebula Sh2-211 it makes up what has become known as the Tribble Nebulae, so called because they look like the furry creatures first introduced in the Star Trek episode "The Trouble with Tribbles".
The estimated age of NGC 1624 is 4 million years.

NGC 1624 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere.
The nebula is visible as a faint, round haze.

The best time to observe NGC 1624 is late dall or early winter.
