NGC 6229 A distant globular cluster

NGC 6229 is a rarely imaged globular cluster located 100 000 light years away from Sun, almost 5 times farther than M13, in the outer halo of our galaxy. Its age is estimated to be about 14 billion years. It is thought that "NGC 6229 could also be the remnant core of a former dwarf spheroidal galaxy".

Due to the large distance the apparent diameter of the cluster is just 4 arcmin. William Herschel added this cluster to his catalog as H IV. 50, where IV actually stands for "Planetary Nebulae". His telescope could not resolve the cluster.

Nights are becoming shorter at our latitude and during the three night the telescope was able to gather only about 3.5 hours of light frames per night.

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.
