NGC 2169

This object is an open star cluster located 3000 light years away in the constellation of Orion at a declination of +13 degrees. This magnitude 6 cluster of 30 stars spans 6 arc-minutes in our apparent view, which corresponds to a diameter of 5 light years.

This cluster's most striking feature is what it doesn't have - nebulosity. There must be little dust in this area. The cluster's lucida is the blue 7th magnitude multiple star Struve 848.

Stephen James O'Meara captures two ends of the spectrum of famous observers' impressions of this interesting object:

- From Walter Scott Houston - "Were this object not already in the NGC, I would never have recognized it as a cluster."

- From Admiral William H. Smyth - "These gatherings awaken still more our admiration of the stupendous richness of the Universe, in every department of which there appears such a profusion of creation, if we may so express ourselves of the works of the Almighty, in which our utmost ken has yet never detected any redundancy, much less anything made in vain."

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
