Horsehead nebula

Revision title: Horsehead, with BXT2 (and a bit of photoshop)

Slowly getting more into the possibilities of APP. I managed to get a separation between Alnitak and the star that is right next to it, but usually get blown by the brightness of Alnitak.

In the first version Stretching and Star Reduction were done in APP, Affinity was used to increase the brightness and get the colours more to my liking. And finally a touch of Topaz Denoise to decrease the noise while maintaining sharpness (which was not very good to begin with). I still have some star deformation caused by back focus (I think).

In the second version I did the stretching in PI using GHS. Unfortunately BlurXterminator worsened the shape of the stars, so I still have some work cut out there.

Title: Horsehead, with BXT2 (and a bit of photoshop)

Description: I made a new attempt with BXT2 but ended up with dark partial halos around my brightest stars if I use the default settings of BXT. So I turned sharpening down, which helped, and removed the remainder of the halos with PhotoShop remove tool, and that was awesome to use! Since this picture was taken without autofocus, I still needed some star reduction to make the stars look less bloated and to make sure that you can see the second star of Alnitak. And I am getting better at GHS, at last.

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.
