NGC6229

Acquisition type: Lucky imaging

This is a lovely little GC in Hercules. Quite pretty, with nice colorful mix of blue straggler stars and yellow stars. The cluster is larger than I expected, but I didn't pick up as much of the outer regions of the cluster as I would have expected. Seeing was ok, but wind posed a problem that distorted star shapes a bit, which didn't help when trying to capture the outer stars in the cluster. I had to do some processing to remove the slightly stretched stars. Despite this, the limiting magnitude here is still about 20.5.

Each of the two image stacked to produce this view is composed of 600 one second exposures live-stacked in Sharpcap. Two second subs would have shown the outer cluster regions more clearly and with more color, but I had to stick with one second subs because of the somewhat windy conditions.

Other items of interest in the image:

At the top of the image is LEDA 2301359, a nice little face on spiral sporting bright outer ring of intense star formation.

At the right of the cluster are two faint galaxies, the upper being an AGN galaxy, LEDA 3096513, and is which is about 670 million light years away. The galaxy has an intensely bright active nucleus that nearly overwhelms the light from the rest of this little galaxy.

Also, not the anonymous compact cluster of galaxies hiding in the light of the rightmost of the two bright white stars at the lower center of the image.

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.
