Revision title: Astrosharp and noise reduction

I thought I'd have another crack at this and get more of the popular elephant trunk than I did last time. In the past I have also imaged this with my SCT (at around 800 mm FL) and with the help of published references described the protostars that are burning holes in this molecular dust pillar. Extraordinary that intense radiation from HD 206267 (to the right of the pillar) is responsible for all this. Lying 2,400 LY away it is an easy target and looks good in narrowband filters.

Here, my L-eNhance dual/tri band filter with predominantly 3m exposures and 3 x 10m exposures. Apart from the increased signal, tracking looked exactly the same (imperfect as always in my star tracker mount, but pretty amazing given all). I like the depth and generally the star colour and UV glow around the pillar.

Anyway here it is, warts 'n all, in 2 hours 40' under a brightening moon.

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.
