What is RC-Astro XTerminator?
RC-Astro XTerminator is a specialized plugin for the astrophotography image processing software PixInsight. It uses neural networks to precisely and efficiently remove stars from astronomical images. The tool is primarily aimed at users who want to edit complex deep-sky objects without the visual interference caused by bright stars.
The functionality is based on AI-supported analysis that differentiates between star-like structures and actual nebular structures or galaxies. Unlike manual or classical mathematical star reduction methods, XTerminator preserves the details of background structures and prevents artifacts in areas where stars were previously present.
The tool is integrated as a locally installable plugin within PixInsight, enabling a seamless workflow in image processing. After applying the plugin, the result is available as a separate layer, allowing the user to re-add the stars later or edit them separately. It is a standard tool in modern astrophotography for high-quality image processing.
Core features & strengths
- AI-based Star Removal — The plugin uses advanced neural networks to precisely isolate stars from deep-sky objects. This allows for clean separation of image content without damaging fine nebular structures.
- Seamless Integration — As a native PixInsight module, XTerminator fits directly into the existing process workflow. Users can apply the tool like any other filter within the software and evaluate results in real-time.
- Preservation of Image Details — Unlike conventional filters, the AI logic ensures that the underlying structure of galaxies or gas nebulae is preserved. This minimizes the need for time-consuming manual masking work.
Who is this tool for?
The tool is aimed at advanced astrophotographers who use the software PixInsight to process their deep-sky images. It is ideal for users looking to reduce their post-processing time and achieve professional results.
Typical use case
An astrophotographer has captured an image of the Orion Nebula, which is overshadowed by very bright foreground stars. To process the faint gas structures with high contrast, he applies XTerminator. The tool removes the stars almost completely from the image, saving the star mask separately. Now, the user can optimize the nebula using histogram transformations and color saturation without over-saturating or distorting the stars. Finally, the stars are re-integrated into the optimized image to achieve an aesthetic final result.

When a different tool fits better
XTerminator should not be used for wide-field star field images where the stars are the primary subject. Likewise, the tool is not designed for processing non-astronomical images, as the models were trained specifically on the characteristics of stars.

Supported languages
Software interface is in English; documentation and support are provided in English.
Interface = the tool's menu language, content = the language you can work in. Without guarantee — vendors keep expanding their language coverage.
Privacy & GDPR
Data flow: Image data processing occurs locally on the user's machine within the PixInsight environment.
Training on your inputs: Input image data is not used for training the AI models.
For companies: There are no specific enterprise contracts; the standard EULA applies to all users.
Practical advice: Since processing is local, any private astro-photos can be processed securely.
- On-premises / local:
- The model runs on your own machine or server. Data never leaves your network — the safest option from a privacy standpoint.
- Training on user data:
- Your inputs may feed into future model versions. Confidential content could in theory resurface in other users' answers.
