M28 a globular cluster in Sagittarius

I had no idea what I was going to image. I looked around the sky and I noticed that

Sagittarius was moving toward the West and was lower in the sky than it had been this

Summer. It would not be in the sky much longer this season so I decided to image M28

and if I had time I would image M8 and M20. M28 has always been tough for me to

image and process because it is small and is nestled in a very dense, saturated star field.

It is a compact cluster and does not have stars stretching out into the outer regions like

other globular clusters. It's relatively bright but in an eye piece it looks like a fuzzy spot

of light. It's hard to resolve stars unless you're using a very large aperture scope. With all

of that said please enjoy my most recent image of M28.

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.
