Seagull Nebula IC 2177 SHO Hubble Palette RASA 8 (Brandon Tackett)

Seagull Nebula IC 2177 SHO Hubble Palette RASA 8

This was a challenging salvage job from the beginning. I had below average to poor seeing with the S2 and O3 layers. My focus was just slightly off on my Ha layer for half my subs. I had not done any edits after initial integration due to the poor quality.

However, due to the perpetual blanket of clouds in the Midwest over the past 2-3 weeks, I decided to revisit the data and see if I could make anything work. Well, more than half way accomplished my goal. I still struggled to get some odd vignetting in my O3 layer out of the final image which is still present in the bottom right corner.

I will look forward to trying this dynamic formation again next year, but I am content to get out of it what I did.

IC 2177 known as the Seagull Nebula (my kids think it is a Dragon from how to train your dragon) is a predominantly hydrogen emission nebula but also has a fair of amount of oxygen emission. The formation is located approximately 3,600 light years from earth in the constellations of Monoceros and Canis Major. The formation includes several open clusters including NGC 2327 seagull’s head, NGC 2335 at the left wing tip, SH2-297 is another emission nebula on the right wing tip, SH2-295 above the right wing.

May favorite feature is the bow shock causing the wings but also the expanding O3 sphere located off center to the back mid portion of the right wing around FN Cma. From my data it looks less like bow and more likely spherical expansion. From what I could find, the wing structure is thought to be created from successive 3 possible successive supernova. I will have to look into it more regarding the shell near FN Cma, possibly a planetary nebula.

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.
