IC434 and the Horsehead Nebula RGBHa

Every year around January and February, we see hundreds of images of the Horsehead nebula and surrounding nebula.

Why? It's because there is so much to see and be exited about when you capture this target. I always learn more each time I capture and edit this famous object. It is surprisingly difficult to image and to end up with what you hoped to after processing. The big brute is the nearby star Alnitak of course. It spreads is radiation into every part of this nebula and others making it hard to make a clean image.

This image has suffered from Alnitak and it was a challenge reduce the effects, but I am happy how it turned out in the end. A small amount of Ha was added just to bring a little more detail to the image, but not so much as to change its natural colour too much.

I hope you like this recent version as much I enjoyed making it. Imaged from the Complejo Astrónomico at Los Coloraos, Gorafe in Spain using my C11telescope and ASI6200MM camera.

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.
