Then select the first image from the drop-down list on the left-hand side and the second image from the list on the right-hand side. To begin the process, navigate to the “Control Points” tab. This is the most time-consuming part of the entire process and can take more than an hour if a larger number of images (> 20) needs to be stacked. Therefore, control points will have to be set manually in every single image. When dealing with astrophotos, however, the automatic control point algorithm will usually fail, because there are too many stars in the image that all look the same and will confuse the algorithm. When stitching a terrestrial panorama, Hugin can automatically find such structures, called “control points”. In order for Hugin to know how to correct and shift the individual images, the software needs to identify individual structures that are visible in all images. Ensure that only images showing the same part of the sky are loaded. Alternatively, you can go to the “Images” tab and click the “Add individual images.” button. Once Hugin has started, navigate to the tab labelled “Assistant” and click on the “Load images.” button to load all your images into the software. This allows the alignment and stacking of images that were taken without a tracking mount. In principal, Hugin can also correct, shift, and rotate the individual exposures. This is useful whenever several exposures of the the same region of the sky need to be stacked in an attempt to create a single image with high signal-to-noise ratio and high dynamic range. This page explains how to stack astrophotos with the panorama stitching software Hugin. I will keep this page online, though, in the hope that some of the information may still be useful. Note: The instructions on this page have already become obsolete as a result of significant changes in the user interface of Hugin.

Libre Arts is a reader-supported publication. I think David Horman is a little too cautious with this. It’s a release candidate right now, but it’s really useful. The latest series of versions represents a complete rewrite with better blending quality, disk caching, unlimited amount of input images etc. While at that, I’d like to point you to Multiblend v2.0, a drop-in replacement for barely maintained Enblend. Only a source code tarball and a Windows build are available so far. Accompanying utilities like cpfind, cpclean, nona, and fulla also received updates and bugfixes.The Control Points tab probably got most of the changes: improved selecting and moving control points in one go, inverted direction of middle-mouse drag, new 400% and 800% zoom presets, improved calculation of scale factor for magnifier, and more.The mask editor ( Masks tab_ got simplified selection and now allows scrolling a zoomed-in photo with the middle mouse key.The Stitcher tab got a simple Edge Fill option to fill black edges in panorama with homogenous color.People do use it for stitching scanned image together, so the Align split button provides quick presets too:įinally, the Create panorama split button allows easily choosing types of output: Hugin is quite useful for more than stitching panoramas. And if you need to do a specific thing like load images and assuming a full-frame fish eye lens, there’s a split button to do so: Now when you load images, it will only ask you for information if it failed to extract it from photos’ metadata. They provides a kind of presets to simplify accomplishing particular tasks. The most user-visible changes in this release are split buttons in the Assistant mode. This release (see the official notes here) mostly got contributions from Thomas Modes, JohnsWork, and Bruno Postle. However, the few people still working on this project do make regular releases with useful changes. It’s been a long time since Hugin has seen active development. New annual release of Hugin, free/libre panorama maker, has arrived with UX improvements.
