Horsehead nebula IC 434, is a beautiful emission nebula composed mainly of ionised Hydrogen gas that emits red light. The dark shape that resemble a horse head is a dark nebula that hides the stars behind it (B33). On the left, is another Hydrogen glowing gas cloud called Flame nebula NGC 2024. Alnitak star is shining just above the Flame nebula. Alnitak is one of stars that forming Orion belt (The Hunter). Also, this region of the sky contains a Reflection nebula just below the Horsehead nebula. NGC 2023 is a blue reflection nebula, it is composed of clouds of gases that reflect the young stars light to glow in blue light. All those nebulae are about 1500 light years from Earth. Gear setup: ES 102 APO f/7 @ 713mm, F/F zero, iOptron GEM 45, guided by ZWO mini guide scope and ZWO 120MM-S, ZWO 2600MC cooled @ 0, Optolong L-pro & Ha filter.

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.
