- Area Constellation Orionis

M42, Messier 42 is probably the best known emission nebula in the winter constellation of Orion. With an altitude of about 1 degree and an apparent brightness of Mag 4, the nebula is easily visible to the naked eye in the night sky, making it one of the brightest objects in the night sky next to the moon 🙂
The Horsehead Nebula is part of a dark cloud in the constellation Orion, which stands out in front of the red glowing emission nebula IC 434 with a silhouette similar to a horse's head. The nebula is approximately 1500 light years away from Earth and appears to be a quarter of the size of the Earth's moon. Due to its equatorial position, it can be observed from all inhabited areas of the Earth, but because of its low brightness it is only visible with a telescope aperture of 20 cm or more.
Faintly shining in the upper right, Messier 78 (also known as NGC 2068) is a reflection nebula in the constellation Orion. With a brightness of 8.0 mag, it is the brightest reflection nebula in the night sky. The nebula is visible in binoculars and telescopes from an aperture of about 50 mm.
In the top left corner you can see a part of the large Orion Arc, which extends around this region in a high arc.

Taken with a Touptek 2600c and a Samyang 135mm/f2 at aperture f4. The small setup was carried by a Skywatcher Adventurer GTi, guiding was done by the MGEN3. Images in RGB and Duo Narrwoband with an Antlia ALP-T filter.
A total of 128x 1s, 64x 30s & 32x 180s lights for RGB as well as 32x 1s, 64x x 30s, 64x 180s, 32x 600s Light DuoNB. Processed in Pixinsight & Photoshop. Core combined using Blend in PS.

Shooting conditions:
Mostly clear nights, occasionally a hazy cloud. Directly from the city with Bortle 7 sky and significant light pollution. January-March 2024.

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.
