IC1396 - The Elephant's Trunk Nebula (Henny Veerman)

IC1396 - The Elephant's Trunk Nebula

Revision title: Improved processing

Finally finished this image after a long period. This is my first result with the Optolong L-eXtreme filter and I wanted to make sure I captured sufficient data. The total integration time left after selection was more than 27 hours, which was the most data I have captured on a target so far. I processed the image a number of times until I was satisfied. I added some improved steps to my processing guide on deconvolution and noise reduction thanks to the Youtube tutorials from VisibleDark which really helped improve the result a lot! I kept the Ha and Oiii data (red and green channel respectively) and generated a simulated HSO palette using a synthetic green channel from the Ha and Oiii (method by Thecoldestnights.com). I am really happy with how the image turned out, although the star color is quite uniform blue which you see often with this filter. I tried using StarNet++ to do starless processing but unfortunately I just can't get it to do a good job. While the starless images look fine after some clone stamping, the extracted star images just have a weird structure to them, especially bigger/brighter stars. Still, the starless images are nice for mask creation. Anyway, I hope you all like the result. Feel free to give advice on how to further improve!

Title: Improved processing

Description: Since the weather hasn't been cooperating lately, I decided to re-process some older data. I tried to apply some of the new techniques I learned on my IC1396 data set. New tools from RC Astro (BlurXTerminator, NoiseXTerminator and StarXTerminator) especially helped a lot in the processing. StarXTerminator finally (for the first time) allowed me to do some real starless processing. Up until now StarNet never gave me good results when extracting stars. I am really happy how the image turned out. The stars look more natural and the nebulosity also looks more smooth.

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.
