The Horsehead Nebula (IC434)

I started astrophotography 7 years ago, and ever since this beautiful nebula has been on my list. For some reason, I never managed to photograph it properly.
This project spanned over 1 year. I took the Ha images back in February 2023, at the time Orion was getting lower on the horizon, and I never got the time... I mean weather... to capture RGB data.

A couple days ago, I finally took advantage of a moonless night to do it, and merged the Ha and RGB data into one picture. I struggled quite a bit to obtain a color balance that works, and ended up using only a fraction of the Ha... I initially thought I'd just add color to my Ha, but it turns out I added a bit of Ha to my color image!

I like it that way though, the nebula looks more natural and not overwhelmed with red. Of course the dreaded microlensing effect of the ASI1600 is visible in all its glory, but I don't mind, I got the picture I wanted!

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.
