NGC 7129

This object is a reflection nebula located 3,300 light years away in the constellation Cepheus at a declination of +66 degrees. This nebula spans almost 9 arc-minutes in our apparent view, which corresponds to a width of about 9 light years.

The intense star light from a young open cluster of about 100 stars is responsible for illuminating the surrounding gas and dust clouds. The faint small reddish crescent shapes in this object are Herbig-Haro objects, ionized hydrogen gas compressed by shock waves from energetic jets streaming away from newborn stars. About 30 HH objects have been identified in this object.

I find this object to look both beautiful and a bit scary. I see several pairs of eyes staring at me through the mist. I love the subtle blue, orange, and pink colors. The shapes of the small reflection and HH nebulae are fascinating to me.

I also captured Ha subs for this object but the signal was smaller than I expected and it did not really add anything to the image.

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.
