NGC6914, VdB-131 and VdB-132 nebulae, LRGB-Ha and RGB (AnaTa)

NGC6914, VdB-131 and VdB-132 nebulae, LRGB-Ha and RGB

NGC6914, VdB-131 and VdB-132 nebulae are surrounded by many different bright (LBN) and dark (LDN) nebulae. These nebulae are Annotated (see Panel E). However, this area is recognized for the three blue reflection nebula - NGC6914, VdB-131 and VdB-132. This beautiful nebula complex located in the center of Cygnus constellation and lies about 6000 l.y. from the Earth. This nebula complex was discovered by Jean Marie Edouard in 1881 and in 1966 Van Den Bergh added two of the three reflection nebulae to his own VDB catalog. The picture contains Parsamian 22 – small bipolar nebula. Magnify panel E, look little bit below vdB -131 (7 o'clock) on a border of the NGC6914 annotation circle. The small double greenish nebula is Parsamian-22. There is also V1515 Cygni FU Orionis variable star with distinctive visible shell. Look 10 o'clock at the edge vdB-131. It has distinct shell.
Overall, just magnify picture and study it. SNR of the object is enormous and is about 2000.

Processing:
Dynamic crop for R, G, B, Lum and Ha
RGB combination
Seti Auto DBE on RGB, B, Lum and Ha
Blur and Noise XT on RGB, B, Lum and Ha
Star XT on RGB, B, Lum and Ha

RGB processing:
This processing is straightforward.
Linear HT stretch on RGB with stars.
Noise XT
Stretch again.
Red and blue mask were used to enhance and saturate reddish and bluish regions and stars, respectively.
Mask off
Annotation is the panel E
RGB image is the panel D.

LRGB-Ha processing:
Stretch RGB stars, RGB-star-less using linear HT
Ha, B and Lum were stretch using GHS
Create LRGB
Save tiff files for LRGB-star-less, Ha and B.
In Photoshop add Ha (90% red+10% blue) and B (70%blue + 30% green) to LRGB-star-less using lightning blend mode.
Back to PixInsight
LHE with 40 and 150 Kernel (setting 0.15-0.2)
MLT_sharp with mild setting
Red and blue mask were used to enhance and saturate reddish and bluish regions, respectively.
Mask off
Add mildly stretched RGB stars
This is the panel C (original)

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.
