Jellyfish from the City (Mostly) IC443

My intent was to capture this as a mosaic with my CDK14 at SRO, but there have been maybe 10 hours this year that I could shoot from SRO due to incredibly bad weather. So with 4 clear days in Portland Oregon, I trotted the FSQ106 and my STT8300 out to my city backyard to get this last narrowband object of the season.

The image contains 14.66 hours of FSQ106/STT8300 data from Portland + 3 hours I found from my old Los Angeles backyard. I had 7.66 hours of data on just the central section taken with the CDK14 and STX16803 from SRO.

Though there were 4 different camera orientations and 2 vastly different image scales, CCDStack was able to register and integrate all of the data.

The mix here is Ha for luminance, SII for Red, SII+10%Ha+OIII for Green, and OIII for Blue. As is typical of SNR's, there is a bright OIII shell just outside the main shock front. To preserve that, I added OIII back as a brighten layer much like we add Ha to galaxies. The blue/cyan gasses on the right are blue because there is some OIII reflection there and there is no SII to color the area. In truth that would be red from Ha but then almost the whole thing would be red in broadband.

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.
