Sadr region in Cygnus with NGC6888

The Sadr region in Cygnus taken with a RedCat 51 and the full frame OSC camera ASI6200MC Pro. The OPT Triad Ultra filter allows to shoot Halpha and OIII in narrow band at the same time, which is convenient as due to whether conditions and summer period not much imaging time is available.
The image is a composite of 300s subframes for the nebula and 60s subframes for the stars.

I had to struggle for some time with camera tilt, but once adjusted properly, stars are almost point like even in the corners of the full frame - resulting in huge images, sorry for that

The image processing workflow followed in essence Cuivs recent video on multiband OSC image processing - thanks Cuiv!

Description: Reprocessing of the same data with better workflow and including some subframes which were excluded in the first version. Even the Cygnus Soap Bubble is faintly visible nearby the Cresent Nebula - can you spot it?

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.
