M13 (Ryan Carroll)

M13

Revision title: M13 redone with blurxterminator

M13 shot through my C11 with .7 reducer/flattener.

This was a fun one to edit. These are 60 seconds subs on my ASI294MC pro at unity gain(120) , offset 30, temp -10.

To process I calibrated with dark and calibrated flats.

After processing I stacked and integrated all the data.

For a detailed process the image used Pixinsight with some minor adjustments in photoshop.
I ran image solver to use SPCC. After I color calibrated I began stretching the image. I first did small stretches with histogram transformation until the core of this cluster was to the brightness I wanted. To not completely blow out the core I then used the GAME script to create a mask for the core stars I had visible. I then inverted this mask so I could bring out the fainter stars on the edges. As I was stretching the outer edges I noticed the middle of the cluster was getting to bright so I again ran a GAME script to create a larger mask and invert so I could work on the faintest stars in the cluster.

After I had this blended to where the brightness was mostly uniform I ran a light ACDNR to reduce some of the noise and saved the image as a 16bit TIFF.

I then went to photoshop for some final touch ups.

Here I did a bit of levels tweaks to get the background brightness where I wanted. I then opened the camera raw process to do some color noise reduction, contrast, dehaze, and clarity of the image. I also did a slight masking of the central area to boost the saturation of those stars as they looked white.

I hope you enjoy this and I am always open to pointers. I often just explore what may work and occasionally have success.

Title: M13- The Great Hercules Globular Cluster

Description: a re-edit with different stacking. I noticed some pretty terrible artifacts around the stars. I stacked with sigma stacking and like the stars better here. Hope you like the change

Description: I am beyond impressed with this new action. Only sad I didn't star with it sooner. The results are just incredible

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.
