Best viewed in full resolution

VDB130 in the Sadr region (part of Cygnus), not commonly imaged, located between the Crescent and Butterfly Nebula.
The reflection nebula is associated with young stars in the surrounding cluster.
The intricate filaments in the center of the frame were the highlights I thought.

I did find the processing this one quite challenging and spent a good part of a day trying to get to this iteration.

The integration times here were longer than I usually needed but luckily the clear summer nights afforded the extra time.

Seeing was exceptionally good with some subs down to 1.8". This allowed resampling to be kept low at 75% to achieve the high resolution since the SNR was relatively high thanks to the fast f/4.75 configuration and the low read noise of the QHY600 at gain56 in high gain mode.

The uncompressed file was 717MB with over 60Mpixs, it had to be downsampled and compressed to be uploaded.

The 3nm filters helped isolate the nebulosity quite well despite the bottle 6 skies.

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.
