IC1396 SHO

Revision title: IC1396 Narrowband Color Mapper

The past 3 nights I've had decently clear skies. Unfortunately one of the nights I set up my plan on the ASIAIR wrong and didn't get any data, but the other two worked just fine. I've been really enjoying narrowband imaging and processing. The framing could have been better here, but oh well. I'm not sure which I like better, with the stars or without.

Also I'm not sure why there's some vertical lines down the center near the trunk. I don't see it in any of my subs. Could it be that I'm lazy and don't usually take flats? - See the description of Revision D.

Title: IC1396 (Better stars)

Description: I've gotten slightly better at processing so my stars look more natural in this revision than the original revision with stars.

Title: IC1396 (Fixed vertical lines)

Description: Thanks to a post here on Astrobin, I finally fixed the vertical lines that were plaguing a couple of my images. Since I had to restack and everything, I did change the processing up a bit, and at least to me it looks better than my original even discounting the problem.

To see the post that helped me go to - https://www.astrobin.com/forum/c/equipment-forums/pleiades-astrophoto-pixinsight/strange-vertical-lines/

If you're not sure about what lines I'm talking about, in the past revisions you can see them especially around the tip of the trunk. They were much more apparent in the masters.

Title: IC1396 Narrowband Color Mapper

Description: I decided to try the new Narrowband Color Mapper script to see what I would come up with. I also used GHS to stretch. Both tools are new to me, and as I'm working on a long term project when skies allow I used some older data to play around with.

NBColor Mapper is an interesting script, and there's infinite possibilities really with how people would colorize their images. In this particular one, Ha is red, Sii is a kind of orange color, and Oiii I picked a lighter blue color. I then ran ABE and BlurX. StarX so I could work on them separate. Histogram Transformation on the stars image, and GHS on the starless image. Played around some more in curves and color saturation. Put the stars back in, ran NoiseX, a bit more curves, and I had a finished image.

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.
