IC1396 - OIII Only

Not something you see every day here. This is the OIII channel of the project I have in process. Basically the companion data to the HA I already shared.

SII is finishing up, and I will share a post of that as well, since I think it is interesting to compare.

Note: There is a UV Emission Source, Lan440 in the upper right quadrant of the image.

Lan 440 (unistra.fr)

If anyone knows more about it, I would be curious to hear. This is not present in the HA and SII data at all, but the OIII seems to have picked it up nicely.

Per Aladin, it is Mag 19.5!

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.
