Horse Head / Flame in Ha

A hydrogen alpha image of the famous horse head and flame nebulae. Image data captured with a Tak TSA120 @ F5.6, QSI 683 CCD camera and Astronomik 6nm Ha filter. Total acquisition was 23 subs @ 20 minutes per sub. Image processing in Pixinsight 1.8.5.

Well detailed Ha images presented in grey scale can be quite special and present more detail than may be obtained in colour images. This is particularly so in areas of busy nebulosity such as present around Barnard 33 (the Horse Head) and NGC 2024 (the Flame Nebula).

Edit: Added Version B to improve contrast of nebula. Applied a star mask in Pixinsight and a small amount of Local Histogram Equalisation.

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.
