Cederblad 51

This image captures a series of objects located in the constellation of Orion at a declination of +12 degrees.

The red emission nebula is the northernmost extent of Sh2-264. This nebula, nicknamed "Orion's Head" for its location at the top of the Orion constellation, is over 3 degrees in diameter. Most of this nebula is off screen, with the center located above the image.

The blue reflection nebula is Cederblad 51, located about 1300 light years away. This nebula is 3 arc-minutes in diameter, which corresponds to a width of just over 1 light year. The nebula is surrounded by the large dark nebula which is designated as Barnard 30.

The final object is the most interesting, and one of a number of Herbig-Haro objects in this area. HH176 is the tiny but distinct red spot at the center of the Cederblad 51 nebula. This object is seen in the full resolution view.

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.
