The true magic of the DSE script lies in its ability to bring out details that might otherwise remain hidden in the shadows. What If I told you, that with just a few clicks, your image can transform from a flat and dull representation of the night sky to a vibrant, detailed masterpiece?

Adaptable and Flexible: The DSE script is versatile. Whether you're working with images that have varying levels of darkness or different types of celestial objects, the DSE can be fine-tuned to achieve optimal results. Users can adjust parameters like the enhancement amount, scale of structures, and the scaling function.

Mask Extraction: An added advantage is the option to extract the mask used during the enhancement process. This mask can be pivotal in further refining the image.

For those eager to dive into the practicalities, here's a step-by-step guide to discover the power of the DSE script.

Navigating the intricacies of PixInsight can be hard for beginners but don't worry, we've got you covered. The A to Z of PixInsight series is a comprehensive guide that takes you through the basics to advanced techniques inside the pixinsight workflow like DSE.

Access the DSE script via the Process Explorer's search bar or the script menu item.
Under the utilities option, you'll find the Dark Structure Enhance script.

Note: The DSE script does not come with built-in documentation, and the property browser Description field lacks additional information. However, this guide will cover all the options the script provides.

It takes only a few seconds to execute the DSE on an image. But before you do that, let's look at the various sections of the script:

This section allows users to select the view for the DSE script. A word of caution: avoid selecting preview windows as this can lead to errors. The dropdown lists all available views in all workspaces, including Preview windows. If a preview window is chosen, the script will produce an error.

Here, users can define layers to remove, extract masks, and choose the scaling function. The "layers to remove" parameter determines the size of structures that will be ignored by the DSE script.

For instance, a default value of eight means structures of eight pixels or smaller will be removed. This helps in reducing noise introduction during enhancement. The "extract mask" option outputs the generated mask used during the process, which can be useful for manual adjustments later on.

The "scaling function" option provides two choices: the default five by five B Spline function and the three by three linear interpolation function. Each has its characteristics and impact on the mask generation.

This section lets users control the DSE algorithm, adjusting the amount parameter and setting the number of iterations. The "amount" parameter determines the blend of the transformed image with the original. 

For instance, a value of 0.4 means the final image will be 40% transformed and 60% original. The "iterations" parameter allows the DSE process to run multiple times successively, enhancing the details further with each iteration.

When it comes to astrophotography, experimenting and tinkering with settings can lead to stunning results. It's like being a scientist in a lab, exploring the unknown. Here are a few tips to take your DSE game up a notch:

PixInsight workflow allows users to decompose images into layers, revealing structures of different sizes. This script can be accessed from the Process Explorer and provides insights into how the DSE script perceives the image.

The extracted layers can be inspected individually, and the script doubles the pixel size with every layer. This understanding helps in fine-tuning the "layers to remove" parameter in the DSE script.
