Orion's Belt

Orion's Belt is an asterism of three bright stars in a straight line. The area has a ton of stuff going on starting with Barnard's Loop (red nebula in a curved line) top left, M78 (looking like a pair of glasses) also top left, Orion's Belt itself with the Horsehead and Flame nebula on one of the stars, the Orion Nebula close to the center off by 8 o'clock, the Witchhead Nebula upside-down on the bottom right and just loads of gases in general throughout the image.

This was shot during a family trip to Pulau Langkawi right before Chinese New Year. Three nights of clear skies provided ample imaging time. Some complications occurred when a wrench broke off the tripod's z-axis. I had to make do by keeping the camera carefully balanced near the zenith as Orion (luckily!!) passes overhead my location. It took over two days of computing time to combine the stack despite extensive culling of lower quality subs. The integrated image required only minimal noise reduction, something which I was grateful for. Stars near the edges though were affected by coma and chromatic aberration but this was to be expected with fast consumer lenses, especially on a full frame camera. Framing was intended to capture the Witchhead but Barnard's loop can also be traced around the edges (camera wasn't Ha modified so some nebulosity was lost there).

Shot at 70mm F2.8 @ ISO1600 using a static tripod following the NPF rule.

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.
