IC 2177 Seagull Nebula RGB

Captured over multiple nights at the end of another imaging sessions to make the most of the night.

Captured on 27, 28, 29, 30, 31 December 2021 from my backyard and Calar Alto, Almeria, Spain. The best data was gathered at Calar Alto due to being 2,000 meters ASL.

The original intention was to only capture enough data for stars to be used on my narrow band SHO version, but I think the results are good enough to show how much detail can be achieved from only a few hours of data.

During capture at Calar Alto, the rotator shows signs of camera tilt, later diagnosed to some screws inside the rotator becoming loose. The star shapes were elongated and needed a bit of treatment in PixInsight using the motion blur PSF tool. Not perfect but better than leaving them as streaks.

Subframes details:
44 x Red 180 sec : 2h 12min.
44 x Green 180 sec : 2h 12min
32 x Blue 180 sec : 1h 36min

Calibration:
20x Bias and Darks.
20 x Flats per filter for each imaging session.

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.
