PixInsight 1.9 Lockhart

Pleiades Astrophoto PixInsight 1.9 "Lockhart" introduces major updates to the astrophotography processing platform, featuring improved performance with AVX2 and FMA3 optimizations for modern x86 processors. The release integrates the Multiscale All-Sky Reference Survey (MARS), offering advanced tools for gradient correction and background modeling, significantly enhancing image quality. Updated system requirements include SSE4.2 support and a recommendation of 64 GB of RAM for optimal performance. This version also discontinues support for older processors lacking AVX2/FMA3.

The PixInsight 1.9.0 installation packages, along with an initial set of MARS database files, are now available for download through the Software Distribution System. These files form the foundation for several key features included in this version, enhancing the software’s capabilities for both novice and experienced users.

PixInsight 1.9 Lockhart version details

One of the central highlights of this release is the introduction of the MultiscaleGradientCorrection (MGC) process. The MGC tool is an implementation of the MGC algorithm developed by Vicent Peris and has been refined for enhanced performance and accuracy. This process creates a gradient model by analyzing statistically compatible, large-scale structures in the target image and comparing them to a gradient-free reference.

Users have the option to supply their own reference image or generate one using synthesized data from the MARS database. This flexibility makes MGC a valuable tool for addressing gradient correction challenges across a variety of astrophotography scenarios.

The MGC process has been designed for ease of use, with default parameters optimized for deep-sky images commonly acquired with amateur astrophotography equipment. These settings allow users to achieve accurate results without requiring extensive adjustments. For more advanced users, the tool includes additional customization options, enabling precise control over its application to unique imaging datasets.

MARS database integration

PixInsight 1.9.0 marks the initial integration of the MARS database, a new resource designed to enhance gradient correction processes. The database provides synthesized reference data that can be used in conjunction with tools like MGC. This capability expands the software's utility by offering a reliable source of gradient-free data for comparison, even when users lack a suitable reference image from their own collection.

Future updates to the MARS database are planned, with the goal of further improving its effectiveness and expanding its use cases. This release represents the first step in what is expected to be an ongoing effort to integrate external data resources into PixInsight’s toolset.

To help users get started with the new MGC process, Pleiades Astrophoto has released an introductory video tutorial on the official PixInsight YouTube channel. This video covers the tool’s features, provides step-by-step instructions, and offers insights into best practices for achieving optimal results.

For those seeking detailed information about all the updates and features included in PixInsight 1.9.0 Lockhart, the official announcement is available on the PixInsight Forum. This resource outlines the changes in greater depth, providing a comprehensive overview of the new tools and enhancements.

PixInsight 1.9.0 Lockhart reflects the development team’s ongoing commitment to advancing astrophotography software. The inclusion of tools like MGC and the integration of the MARS database demonstrate a focus on addressing practical challenges faced by astrophotographers, while also paving the way for future innovations.

This release is part of PixInsight’s broader effort to provide a robust platform for image processing and analysis. By combining cutting-edge algorithms with user-focused design, PixInsight continues to be a leading choice for astrophotography enthusiasts and professionals worldwide.

The PixInsight 1.9.0 Lockhart update is available now for all licensed users. Installation packages can be downloaded through the Software Distribution System, which ensures access to the latest version for users on supported operating systems.

The new version of PixInsight is here and it finally brings MARS to life, which means amazing gradient correction! Have a look at all the new features and how to use them!
