In the final part of this workflow a few last enhancements as well as noise reduction are applied. This is an optimized video that should have a reasonable playback experience.

Here is where it comes together. The RGB and L images are blended together. The technique of what to look for is demonstrated. This video has been "optimized" for play back as part of an on-going effort to test better performance. Please let me know if the video still suffers from failures to play.

A small explanation of the new GAIA local star catalogue and a bug to avoid.

(this section will likely be stale when the bug is fixed.)

The all important moment when the images of stretched permanently. Sometimes it isn't a perfect fit... but this lesson and the next demonstrate what to look for and how to reach your goals.

Dynamic Background Extraction of the RGB and Luminance images. (It is OK to do this after deconvolution in this case.)

A great example of deconvolution demonstrates the PSF script, improving the PSF but then ultimately doing even better with the mathematical PSF. 

Photometic Color Calibration is used on the data with some additional adjustments of Color Match and the minimum filter to help with the out-of-focus red data.

Image Integration of the data requires a thoughtful approach (and rejection choices) when data isn't entirely consistent. A way to navigate this situation is demonstrated.

The stars continue to be aligned in this section which bodes well!

In this second section of the M51 workflow the data is calibrated with WBPP. 

This section introduces the workflow and takes inventory of the data. (Download the data and follow along...)

This page contains a link to download the entire workflow project for NGC 3486. It therefore contains everything I did to the image. There are very few resources of this type out there!

Here are the final steps in this fundamental processing workflow. Nose reduction is the key task. This isn't necessarily the end of the adjustments that can be made- but getting to this point opens opportunities to further enhance the image. Many of these special enhancements are highlighted in PixInsight Horizons. 

This video demonstrates a method of applying differential color saturation based on hue in order to improve color visibility of features in the object. 

Shown below are is the process Adam typically uses to blend color with luminance data. This method is likely not one that is typically shown... but shows that simple innovations can lead to consistent and beneficial results.

In one of the showiest of the fundamental processing steps, HDRMT is applied to the luminance image in order to gain great contrast in the brightest features of interest and moderate the brightness so that vivid color can be blended in later.

This section features a solution for the removal of a (large) dust mote that still appears after flat field corrections. This demonstration is included for completeness, but is not truly a fundamental step. However, there are *always* problems in the course of processing data and finding good solutions certainly is a fundamental skill to strengthen.
