vdB 137 (also known as IC 5076) is a faint reflection nebula in the constellation Cygnus. It is located in the northern part of the constellation, about 2° north of the central part of the North America Nebula. The nebula is linked to the star HD 199478, a blue supergiant of spectral class B8Iae with strong emission lines peculiar enough to be classified as a Be star. Its apparent magnitude is 5.73, and being a pulsating variable (V2140 Cygni) shows changes in brightness of the order of 0.1 magnitudes. Its distance is estimated to 1750 parsecs (5700 light years).

This image consists of 183 4 minute subs, 12.2 hrs of exposure. This area of the sky is a dense star field rich in size, type, color, and distance.

Title: vdB137 - blurx v2 ai4

Description: Two major changes in this image. BlurX v2 AI4 applied to fix the collimation issue with my stars in the original image. Also darkened the background a touch simply to please me. It looked a bit smudgy, perhaps due to graX, I'm not sure. Still has the hydrogen in the background, just not as distracting. This revision is much more pleasing to me.

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.
