NGC 6207 and Hogg 22

NGC 6204 is an open cluster in the southern constellation Ara, close to the galactic equator. It was discovered on May 13, 1826 by James Dunlop.It is an 8.5 magnitude cluster of Trumpler type I2p situated in a rich Milky Way star field. Nearby is the cluster Hogg 22 consisting of four or five brighter stars.

Helen Sawyer Hogg was an astronomer noted for pioneering research into globular clusters and variable stars. She was the first female president of several astronomical organizations and a notable woman of science in a time when many universities would not award scientific degrees to women. Her scientific advocacy and journalism included astronomy columns in the Toronto Star and the Journal of the Royal Astronomical Society of Canada. She was considered a "great scientist and a gracious person" over a career of sixty years. She was an expert on variable stars in globular clusters and discovered many open star clusters in the southern Milky Way.

It was my pleasure to meet and to work with Dr. Hogg about 40 years ago

when I was doing variable star research for the AAVSO at the David Dunlop Observatory in Toronto. A very gracious lady indeed!

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.
