VdB132 - SHO

NGC6914 - nebula located in the Cygnus constellation near Sadr star. This nebula consist of two objects named as VdB131 and VdB132. This objects shine in the band ionized oxygen OIII. The VdB132 has been selected as main object during photographic session.
LBN279 and LBN292 - huge area with strong emission in ionised hydrogen H-Alpha and H-Beta (not presented on image weaker ionized hydrogen line) and also sulfur SII.
Except of above nebuleas on images can be found many unnamed structures near following stars:
- TYC3160-645-1 (9.1 mag)
- TYC3160-1726-1 (9.6 mag)
- TYC3160-55-1 (9.4mag)
Image has been composited in a SHO pallet, where for RGB channels were assigned:
R - combination of images in filters: SII, Ha and OIII: (OIII^~OIII)*SII+~(OIII^~OIII)*Ha;
G - combination of images in filters Ha and OIII: ((OIII*Ha)^~(OIII*Ha))*Ha+~((OIII*Ha)^~(OIII*Ha))*OIII;
B - OIII
Photographed area characterizes by strong emission in ionized hydrogen and sulfur, but ionized oxygen line is very weak. Next time I have to take it into account and take images in configuration 1:1:3 for Ha,SII and OIII.

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.
