The dark silhouette of the Horsehead Nebula against the surrounding rich HII-region, is one of astronomy’s most iconic images. Surprising then that I’ve never imaged this object in broadband wavelengths before with my mono camera. Therefore, somewhat belatedly and with the benefit of unusually long spells of clear skies, this February I set out to rectify this omission from my astrophotography repertoire.

Whilst B33 the Horsehead Nebula gets most of the attention, this large HII-region contains many other exciting objects. Within the large molecular cloud, located just below and to the left of the Horsehead, is the emission and reflection nebula NGC 2023. Discovered by William Herschel in 1785, at 10 x 10 arcminutes it is one of the largest reflection nebulas, illuminated at its centre by the Herbig Ae/Be star HD 37903 (a pre-main-sequence star). Then, just to the left (north) of NGC 2023 is the dramatic NGC 2024 Flame Nebula, an emission nebula energised by the adjacent and very bright Alnitak star and a cluster of young stars within.

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.
