M1 - The Crab Nebula

This is a false color image using the SHO Hubble Palette. [I shot this two years ago with a DSLR for those interested in a true color version](https://www.reddit.com/r/astrophotography/comments/9xb8jn/m1_the_crab_nebula/)

Captured on October 23rd and 26th, and November 13th and 16th, 2020 from a bortle 6 zone.

**PixInsight Processing:**

* BatchPreProcessing

* SubframeSelector

* StarAlignment

* [Blink](https://youtu.be/sJeuWZNWImE?t=40)

* ImageIntegration

**SuperLuminance:**

* Ha, Oiii, and Sii images were integrated using ImageIntegration and then drizzled (2x, Var β=1.5) to make the superluminance.

**Linear:**

* DynamicCrop

* DynamicBackgroundExtraction

* [EZ Decon and Denoise](https://darkarchon.internet-box.ch:8443/) (Superluminance only)

* STF applied via HistogramTransformation to bring each channel nonlinear

**Combining Channels:**

* PixelMath to make classic SHO to RGB image

**Nonlinear:**

* LRGBCombination with Superluminance

* Shitloads of [Curve](https://i.imgur.com/ms5h9bO.jpg)Transformations to adjust lightness, saturation, contrast, hues, etc

* RangeMasked SCNR to adjust background colors

* ACDNR

* LocalHistogramTransformation

* DarkStructureEnhance

* More Curve

* EZ Star Reduction

* Resample to 70%

* DynamicCrop to 2880x2160

* Annotation

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.
