NGC 6229

Description of NGC 6229 in The Deep Sky Field Guide to Uranometria 2000:
"Magnitude of the brightest stars = 15.5
Horizontal branch stars magnitude = 18.0
Concentration: 4 ( scale 1{dense} to 12{loose} )"
------------------------------------------------------------------------------------------------

Distance from Sun: 99.4 kly
Distance from Galactic Center: 97.1 kly
Apparent Diameter: 4.5 arc min
Globular cluster NGC 6229 was discovered by William Herschel on May 12, 1787, and first taken for a planetary nebula from his visual impression. Thus he cataloged it as H IV.50. John Herschel apparently never observed it, and Admiral Smyth also saw it as a nebula, and mentions that it was taken for a comet in 1819. William Huggins found its spectrum to be continuous. It was only revealed as a "very crowded cluster" by D'Arrest in the mid 19th century. Dreyer's NGC lists it as globular cluster.The difficulty to resolve this cluster becomes reasonable when looking at its large distance of about 100,000 light years.

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.
