Lately I have been playing around with large exposures time for some common objects in order to get rather deep photos and, undoubtedely, M15 is one of the best targets for since it is a rather common target and the amount of hidden nebulosity "around" it is amazing. While you can get a pretty decent photo of M15 with a couple hours, with a couple dozen hours of additional RGB integration you get a vast amount of IFN and, with a couple dozen hours more of Ha, a beautiful Ha field can be unveiled. All of that hidden at plain sight...

This ability to reveal hidden structures using time still keeps amazing me in this hobby.

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.
