NGC 3228

Not every deep sky object can be overwhelming and awe-inspiring. I think this object has a quiet beauty in its simple layout and elegant lack of symmetry.

This humble open cluster of 25 stars is located 1600 light years away in the southern constellation of Vela. It's diameter only spans 2 light years. Discovered in 1755 by Abbe Nicolas Louis de Lacaille viewing from southern Africa, it is one of the earliest southern deep sky objects, predating the Messier list. From my viewing location, this object only rises 7 degrees above the southern horizon.

Note the interesting trio of blue double stars, towards the lower left, upper left, and upper right corners, that look very similar in color and orientation.

The refractors!

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.
