Wide FOV Flame and Horsehead

Revision title: Wide FOV Flame and Horsehead

Obtained with #29 300 second light frames usingan L-Ultimate filter from a Bortle 6-7 area in Cincinnati, Ohio.

This is frequently imaged by just about everyone. Images abound.

The technical difficulties include the bright star Alnitak and subsequent artifacts.

"The Horsehead Nebula, also known as Barnard 33, and its companion, the Flame Nebula, sit near the star Alnitak in Orion’s Belt. Today, we know that the Horsehead is a dark, light-gobbling nebula made of cold gas and dust. And, as Barnard showed, this dark cloud’s signature shape is only visible because its silhouette obscures the light from the brighter nebula behind it."*

Despite several attempts to visually see the Horsehead, I have not.

Title: Wide FOV Flame and Horsehead

Description: This image was obtained with #29 300 second light frames using an L-Ultimate filter from a Bortle 6-7 area in Cincinnati, Ohio.

The Horsehead Nebula, also known as Barnard 33, and its companion, the Flame Nebula, sit near the star Alnitak in Orion’s Belt. This signature shape is only visible because its silhouette obscures the light from the brighter nebula behind it.

Additional imaging time would have provided a better image, I suspect, but it has been a long and cloudy winter. Processing the image is complicated by the bright star Alnitak and I spent a bit of time dealing with this issue.

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.
