Removing gradients from astrophotos gets easier with GraXpert

As an astrophotographer, I've always found the process of removing gradients from my images to be incredibly frustrating. These gradients, often caused by light pollution, can overshadow the beauty of the night sky, making editing a tedious necessity. Thankfully, the new tool from GraXpert aims to simplify this task. It's designed to efficiently clear away these unwanted gradients, allowing photographers like me to focus more on capturing the cosmos and less on post-processing headaches.

Developed under the BSD-3 license, GraXpert offers its source code and binary releases for Windows (10+), Linux (tested on Ubuntu 20.04), and macOS (10.15+) via GitHub. You can download it directly from the official releases page or find out more about the licensing on their GitHub page.

GraXpert was born from the creative minds of hobbyists in the Dark Matters Discord community, with Frank Sackenheim leading the concept alongside Steffen and Christian. Sackenheim, a German astrophotographer, envisioned an affordable gradient removal tool for beginners, and the team transformed the idea into reality within just three months. Their dedication to quality led to this initial RC1 release, and they eagerly welcome user feedback and shared results.

To support the user community, Sackenheim has set up a comprehensive website offering detailed resources. Here, users can find video tutorials in English and German, a written user manual, and direct download links for the software.

Astrophotographers can also engage with the creators and other hobbyists through the Dark Matters Discord community, which maintains channels specifically for GraXpert. Conversations happen in both English and German, providing a welcoming space for feedback and collaboration.

Those interested in reporting bugs, suggesting features, or even contributing to the tool's development can access the GitHub project linked above.
