NGC6910 in Cygnus Region

NGC6910 is an open star cluster in Cygnus. It is the most prominent group of the stellar association Cygnus OB9, and is located in a large Ha region in the environment of the star Gamma Cygni (Sadr). Thus, although it is a small cluster with few stars, it is surrounded by an impressive environment of Ha emission clouds and bright scattered stars. So, I did a long exposure with the OSC camera and IDAS LPS-P2 filter, but I added even more shots with the Ha filter on the same camera. The Ha signal produced an increase in contrast that I've respected to highlight the presence of bands and clouds of dark dust that appear to break the continuity of the emission region. I separated channel B of the RGB image to identify the presence of blue light, and I intensified it slightly to emphasize its presence in the predominantly red background of the Ha emission. The entire photograph shows 2.9 x 2º of arc. The brightest star is Sard, gamma Cygni, which is actually much closer than the rest of the region. The cluster is located in the center of the image, where it occupies 11 arc minutes.

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.
