NGC 6914 (vdB131 and vdB132) and the surrounding nebula (Gary Lopez)

NGC 6914 (vdB131 and vdB132) and the surrounding nebula

Link: https://www.garylopezphotography.com/

This wide field image shows a large nebular complex, LBN 292, in the constellation Cygnus. It is composed primarily of hydrogen and dust, carved and folded by the energy of the nearby stars. At the center of the image are two reflection nebulas, vdB131 and vdB132. Together these two nebula are cataloged NGC 6914.

These data, collected in 2019, are very good quality with HFR ranging from 1.7-2.0 and deserved substantial processing exploration. In my original 2019 post of the SHO rendition of these data I state, “I will be posting alternative processing of these data in the future.” So, three years later, here we go. In this processing effort I employed several new noise reduction, star management, and color palette control approaches that I developed in the last few years. I have posted three images in this processing study, including

Original – RGB with Ha
Combining RGB/Ha luminance image and Ha starless image using NBRGB script in PixInsight.

Version H – SHO starless
Combining starless NB channels (Ha, OIII, SII) and starless master luminance (Ha and SII) using PixInsight LRGB Combine tool .

Version J - SHO with RGB stars
Combining starless NB channels (Ha, OIII, SII) with RGB star map using PixInsight Pixel Math.

These three renditions reveals different aspects of this complex region that has emission, dark, and reflection nebulae features.

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.
