astrophotography archeology - sadr area of september 12th, 2005

This image is the sum of 51 180 secs unguided subs taken on the 12th september 2005 from my home terrace bortle 8 sky, with a modded Canon 300d, a Canon 70-200 F4 lens (brought at 70 FL), an idas LPS2 filter. On top of a Taka skypatrol.

Checking an old hd I have found many forgotten images. I have tried to reprocess this one using modern software.

Stacking with DSS. Gradient removal (2 passes), crop, DDP, white balance, color curves, deconvultion with Astroart 8.

Gamma Cygni (γ Cygni, abbreviated Gamma Cyg, γ Cyg), officially named Sadr /ˈsædər/, is a star in the northern constellation of Cygnus, forming the intersection of an asterism of five stars called the Northern Cross. Based upon parallax measurements obtained during the Hipparcos mission, it is approximately 1,800 light-years (560 parsecs) from the Sun.

It forms the primary or 'A' component of a multiple star system designated WDS J20222+4015 (the secondary or 'BC' component is CCDM J20222+4015BC, a close pair of stars 40" away from γ Cygni). Wikipedia

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.
