NGC6888 The Crescent Nebula

This is a combination of data taken over 2 days. Before this, I had several nights of failed guiding in a row which led to a lot of frustration. I am glad I finally figured it out. Pretty proud considering this was taken at native f/10.

Processing Details:

* All images stacked using DeepSkyStacker

* OIII STACK

* 4 Basic Levels Adjustments to bring out Nebulosity and to darken the sky

* RC-Astro GradientXTerminator @ MediumxMedium

Ha STACK

* 4 Basic Levels Adjustments to bring out Nebulosity and to darken the sky

LUM LAYER

*I took the Ha Stack and added the OIII Stack at 50%. This was done with all of the edits mentioned above

HOO Image

* Ha to Red Chanel

* OIII to Green Chanel

* OIII to Blue Chanel

* Convert to 16BIT using Exposure and Gamma

* Vibrance Layer (+50)

* LUM Layer

* Levels Adjustment

* Color Select Vibrance Layer (+50) to up the red

* Astronomy Tools Local Contrast Enhancement

* Astronomy Tools Star Diffraction Spikes Fat Stars

* Final Crop

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.
