M13 globular cluster in hercules

The best M13 I caught so far. In postprocessing I saw that the 2 bright stars are unfortunately blown out. something to keep in mind for the next time or take a few shorter exposures to blend over.

Description: The core of the clusters seemed a bit too bright to me so I tried an HDR wavelet transform on it. This reveals the stars in the core quite nicely. However it also makes the cluster somewhat flat and 2D.

C

Description: I blended the 2 versions, the one with and without HDR wavelet transform and blended the HDR version on top with 50% transparancy in photoshop. Best of both world i guess:) It reveals the stars in the core and maintains some of the 3D look because of the brighter core.

D

Description: A few bright stars where saturated. In the mean time a learned that convolution can be used to fix ringing artefects on bright stars. And I found that it can also be used to fix saturated stars afterwards. Better to not saturate them in the first place but this works allright

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.
