Barnard 30

Barnard 30 is a dark nebula in the constellation Orion. The Barnard 30 cloud is one of the regions in the Lambda Orionis Ring where the population of young stars is concentrated, together with the Lambda Orionis cluster and Barnard 35. It is roughly 1300 light years from Earth. The stellar population in Barnard 30 is about 2-3 million years old, and is therefore significantly younger than the central Lambda Orionis cluster. This cloud is likely shaped by the massive star Meissa and this star is also responsible for triggering star-formation in this cloud. A possible supernova 1 million years ago that possibly formed the Lambda Orionis ring might be an additional trigger for the star-formation in this region. The region also contains a reflection nebula -- the blue region in the center.

This image is close to natural color, with 13 hours of broadband natural color exposures as the "base," and then enhancing with another 5'ish hours of narrowband Hydrogen-alpha data. Hydrogen-alpha glows red, so I used this data to both enhance the red as well as the structure in the luminance channel.

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.
