M16 Eagle Nebula (LRGB) - 25 Aug 2019

Revision title: Reprocessed using PixInsight.

Here is my look at the 'Pillars of Creation' made famous by Hubble. As expected this proved to be a challenging target from the UK, especially as I was trying for it quite late in the season when it was already setting as astronomical darkness fell. Most of the data was captured before the skies were fully dark. Imaging at such a low altitude and in a less than dark sky contributed to bad seeing, made worse by lots of horizon hugging haze and cloud, consequently guiding was erratic and generally poor resulting in somewhat weird shapped stars, but I'm still pleased to get this in the can.

Title: Reprocessed using PixInsight.

Description: This is a complete repocess in PixInsight, starting with Linear Fit on the 3 RGB channels and use of BlurXT to reduce stars and halos in Blue and Green channels as they were both, the Blue in particular, very bloated compared with the Red channel data. I used GHS to stretch both the combined RGB and Lum channel images, before LRGB combination.

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.
