NGC 7129 in RGB

NGC 7129 is a reflection nebula in the constellation Cepheus, located about 3,000 light-years from Earth. In this deep RGB image, I have attempted to capture the nebula's dusty surroundings, which appear as brown clouds with embedded knots of denser material, or dark nebulae. This field also contains pervasive hydrogen emission nebulae, visible in the red hues. To the upper right of NGC 7129 is the open star cluster NGC 7142. Although separated by half a degree in the sky, these two objects are quite distant from each other, with NGC 7142 located around 6,000 light-years from Earth.

I began this project in early July but didn't complete it as Southern Arizona's monsoon rain pattern dominated the weather. The rain and persistent clouds did not let up until September, when I was finally able to complete data acquisition.

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.
