Seagull Nebula (in SHO with an OSC Camera)

We captured the Seagull Nebula at the beginning of February and after many iterations of processing, we are happy with this result. This nebula region spans 240 light years across and is approximately 3,600 light years from earth. It’s also known by IC 2177, but that’s specifically the area considered the seagull’s head; there are several catalog designations for the area as a whole. In the body of the seagull, you will notice a bright star with a blue arc around it, this is a bow shock from runaway star FN Canis Majoris, which is essentially a star that moves at high velocities in an unusual direction.The image was captured with our OSC camera with a dual narrowband filter over several nights. The image was stacked in APP using the HaOIII-Color algorithm and drizzled by 2x. Light pollution removal and basic color calibration was done in APP as well. We then incorporated Lukomatico’s (via YouTube) process for generating SHO images with an OSC camera in Pixinsight which involves splitting the color channels and recombining them. Topaz Denoise was used to denoise the image and and then Lightroom for final touches on color, saturation, and cropping.

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.
