Horsehead and Flame Nebula in Orion, Narrowband

Yes, it's the most photographed object in the night sky! I tried too shoot this narrowband, which was questionable. There's no Oxygen-III in Horsehead. S-II does add a little to the dominant Hydrogen-alpha. I've got some nasty reflections from the star Alnitak, but not sure why.

1. WeightedBatchProcessing, Subframe Selector, Star Alignment, Local Normalization, Image Integration, Drizzle Integration, Dynamic Crop

2. Dynamic Background Extraction

3. EZ Decon on Ha

4. EZ Denoise

5. EZ Soft Stretch

6. PixelMath to create RGB with R: Ha; G: 1-((1-0.25*Ha)*(1-SII)); B: 1-((1-0.5*Ha)*(1-OIII))

7. SCNR to remove green tint

8. Duplicate Ha to create L, and apply CurvesTransformation to increase some local contrast

9. LRGBCombination to apply L to the RGB image

10. Curves Transformation

11. Clone Stamp to fix upper star, that was wrecked during deconvolution!

12. EZ Star Reduce

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.
