Elephant Trunk Nebula (IC1396) in HOO narrowband

Revision title: A better processing

Here's the results of my efforts from last night, a false bi-colour narrowband HOO image of the Elephant Trunk nebula in Cepheus (IC 1396)! The weather forecast was clear sky for a few hours so I quickly set up my rig, this time with the 135mm Samyang lens. As usual, some compromises had to be made and I stopped the lens down to only f/2.8 in order to gather more light in the little time I had, resulting in some distortion of the stars in the corners and vignetting. In the end, all the data was quite noisy, the H-a data set was a bit better than the O-III. I had to swear a bit the pull out something decent - some colour gradients are still present - but it turned out reasonably nice!

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.
