Orion's Heart

The images captures the heart of the Orion Constellation, Orion the hunter, Orion the great. The bright stars of Mintaka, Alnilam, and Alnitak makes Orion's Belt most known asterisms in the night sky. South of the belt around Alnitak we can see The Horsehead Nebula (IC 434) and Flame Nebula (NGC 2024). To the right of the frame we have the beautiful Orion (M42) and Running man Nebulae (NGC 1973).Images were taken in Valley of Whales National Park in Al Fayoum desert on 2 nights in October for the unfiltered data and one night in November for data captured using the L-extreme filter. Shorter exposure were needed to show the core details which would be blown out in long exposures. The Ha signal from the l-extreme filter was added to enhance the nebulosity in the region.

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.
