VDB 152

VDB152 is a blue reflection nebula that glows at the top of a dark Bok globule B175. It is located 1,400 light-years away in the constellation Cepheus.
Near the edge of a large molecular cloud, interstellar dust in the region blocks most of the starlight behind it or scatter light from the embedded bright star giving parts of the nebula a characteristic blue colour. Embedded in the left side of the nebula is the Herbig Haro object HH 450, a jet emitted from a newly forming star. The thin red filaments of a huge supernova remnant. At the bottom right is Dengel-Hartl 5 is a HII- and OIII-region, ionized by the white dwarf WD 2218+706 (the blue star in the center of the nebula). This is an Ha-LRGB image. The RGB part was shot with a OSC. This project started on Aug 18th, and finished up Sept 3rd that consist of almost 18 hours of time. 8.5 of that is Ha data. This was definitely one of the hardest things I have processed to date.

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.
