September 7, 2017
- Observatory now remains responsive while loading, processing and stacking images. You can even edit an image version’s notes and other metadata during these tasks.
- There is a new “Stop Tasks” toolbar button and “File ▸ Stop Tasks…” menu item to stop image loading, processing and stacking. It also temporarily stops automatic library maintenance tasks.
- The editor and inspectors display progress indicators when appropriate.
- It uses less memory. Stacks can be larger, especially those without layer adjustments.
- When the system is running low on memory, Observatory will now issue a warning. Most of the time the system will be able to handle the tasks just fine and you can ignore it. If it is running critically low on memory, it will issue another warning with the option to automatically stop tasks when this happens. It is fairly conservative with these warnings, and systems equipped with SSDs may be pushed well beyond it.
- Observatory now includes FITS, XISF and SBIG plugins for Acorn. They allow you to import these images straight into Acorn at full bit depth. Use the new “Observatory ▸ Install Extras…” menu item to install them.
- You don’t need to focus on a stack anymore just to see the number of images it is made of. This is now shown on the stack’s browser thumbnail itself.
- There is now a demo version of Observatory, which you can download from our website.
- Editor: The editor displays an error icon and message if a stack or image cannot be loaded or processed.
- Editor: The behavior of selecting an image while holding down the option (
⌥) key has changed. If the key is not pressed, the image is displayed in the standard editor. If it is pressed, it is displayed in the active assistant editor, and the editor’s mode is automatically switched if needed.
- Editor: The active assistant editor is now indicated using the system’s highlight color.
- Inspector: The error handling has been improved for the image statistics inspector and the histogram, and the latter displays an error icon if the image is unavailable.
- Tags: Automatically added tags are now all lowercase and without spaces.
- Preferences: The new “Reset Warnings” button resets the “Do not show this message again” checkboxes of alerts.
- User Interface: The calibration albums in the “Move To Album” and “Add To Album” menus are now at the top level, making it easier to choose them.
- User Interface: Menu items “New Master”, “Export”, “Export as PDF”, “Print”, “Auto-Weight” and the Share button display a progress indicator if the selected images are still being processed. Clicking the “Stop” button will continue the processing, but skip the chosen action.
- User Interface: The “New” menu that was removed from the contextual browser menus in 1.0.6 has been put back. Instead, the less commonly used “Lock” and “Resize Canvas” items have been removed. They are still in the main menu of course.
- User Interface: The “Compact Library…” menu item will ask for confirmation before proceeding.

November 12, 2016
- Observatory now has Quick Look and Spotlight plugins for XISF images, and can import them as well. XISF is the native file format of PixInsight, an image processing software platform designed specifically for astronomical imaging.
- The Image menu and Browser contextual menu have new “Open Master” and “Open Master With” menu items. This allows you to quickly open a master file in an external editor, for example PixInsight.
- Library: It is now easier than ever to create a new library. Just drag the folder containing your astronomical images in the Finder and drop it onto the Observatory application icon. It will create a new library and import all images in the folder and its subfolders. It’s a great way to quickly inspect your latest images, and can serve as a starting point for a much larger library as well.
- Browser: You can drag & drop images from the browser to albums in the library navigator to organize your images. If you press the Option key while dragging, the image version is copied instead of moving it. Currently you can only move images to the albums in the “Collections” section of the library navigator, not the “Library” section. For this to work, the browser should also not be focused on a stack.
- Browser: You can drag & drop images and stacks on top of another image or stack of the same album. This combines them in a stack. If you press the Option key while dragging, the image version is copied instead of moving it. The browser cannot be focused on a stack for this to work.
- Browser: The Image menu has new “Move to New Album” and “Move to Album” menu items. Press the Option key to access the previous “Add to New Album” and “Add to Album” menu items. The corresponding menu items in the Browser contextual menus have been removed.
- Browser: Observatory now actively monitors master images to detect if they were altered or deleted. It updates the image version badges accordingly. If a master image is altered, choose “Image ▸ Reset Attributes…” to incorporate the changes into the library, and remove the badge. There are currently still some limitations to the number of master images it monitors simultaneously, which will be addressed in a future release.
- Browser: A new badge is used to indicate a missing master. The browser uses the previous badge to indicate that a master was altered. This can happen if you open the master with an external editor, and modify it.
- Browser: Weights are now always and only displayed when focusing on a stack. The corresponding subtitle and column selection menu items have been removed. The weight column is now always next to the date/time column, both of which cannot be moved.
- Browser: The date/time column menu item has been removed because this column cannot be removed from the List Browser.
- Editor: For matched images the image scale is shown by default, in addition to the grid.
- Editor: The maximum allowed aperture, gap and annulus values in the centroid settings have been increased.
- Library: The compression ratio for Managed Masters has been slightly improved.
- Preferences: Adjusted the label capitalization style.
- User Interface: Adjusted the font size in the inspector dropdowns.
- User Interface: Increased the width of the image and collection name field in the inspectors. Now the favorites, archive and trash icons are rendered behind this field, when applicable.
- User Interface: Enhanced the application icon at small sizes.
- User Interface: Observatory libraries have a new icon.
- User Interface: One icon is now used for FITS and SBIG images, as well as for XISF images. The latter is used only if PixInsight is not installed.
- User Interface: The “Observatory Blog” menu item has been renamed to just “Blog”.
- Library: “Reset Attributes…” uses much less memory, and is more efficient when multiple image versions are selected.
- Library: Fixed an issue with the creation of a Managed Master when using “Image ▸ New ▸ Master”.
- Import: Improved handling of invalid binning, pixel size and pixel scale values.
- Import: Fixed an SBIG date/time handling issue.

- Inspector: Fixed an issue that made it impossible to change the CCD temperature in the image version inspector.
- Inspector: Fixed issues with duration and length unit conversions.
- Spotlight: Fixed a mixup in the FITS and SBIG Spotlight Importers that may prevent them from working properly.
- Spotlight: Now including the “Content Created” item in the Finder “Get Info” window so it actually displays the exposure date/time.
- Spotlight: Fixed an SBIG date/time handling issue.
- Crash: Resolved a crash that sometimes occurred when switching to Virtual Observatory immediately after opening a library.
- Crash: Resolved a crash that could occur if a managed master or image version was damaged or missing.
- Crash: Image thumbnail generation and stacking are now more robust against failures. Together with the previous issue and in combination with state restoration, it could prevent Observatory from fully launching.
- Leak: Fixed a memory leak in the Blog update notifier, inspectors and a potential leak in the channel pixel data handling.
September 14, 2016
- Browser: When you select a folder, album, or smart album, the browser displays a Focus Bar. It contains the name and type of the selected collection, and allows you to traverse up the collection hierarchy using its “Unfocus” button.
- Browser: Instead of expanding stacks inline, the images comprising a stack are shown when you focus on the stack with the Focus Bar. When focused on a stack, the Focus Bar displays three handy buttons to quickly select the stack’s pick image, all images comprising the stack, or the stacked image itself. With the “Unfocus” button you traverse up to the stack’s album.

- Virtual Observatory: Under certain circumstances not all archives were initially selected for a newly created library.
- Virtual Observatory: Fixed a search results selection issue when sorting.
- Import: The album hierarchy created when importing folders of images generated superfluous folders.
- Import: The right ascension, declination, latitude and longitude FITS keyword parser sometimes failed to parse the (arc)minutes and (arc)seconds correctly, resulting in values of the form “NN 00 00.0” in the inspector. This has been fixed. To resolve this for images in existing libraries, select them in the browser, and then choose “Image ▸ Reset Attributes…”. Please be aware that this resets all attributes to those of the master image, not only these four.

- Crash: Resolved a crash that occurred when the expected files of the UCAC4 or USNO-A2.0 catalogs were not accessible.
August 3, 2016
- Spotlight: Observatory now includes Spotlight Importers for FITS and SBIG files. This means that, when choosing File ▸ Get Info for such files in the Finder, it will now display useful information like image dimensions, exposure time, detector temperature, right ascension, declination, etc. What’s more, you can now search for this information right from within the Finder itself!
- Library: When creating a new library, you now will not be asked for its name anymore. You only need to provide it when explicitly saving it. This is more convenient and consistent with other applications that support Auto Save. More importantly, this makes Observatory fully compatible with the new Tabs feature of upcoming macOS Sierra.
- Library: Disk space utilization for layer stacks has been optimized. For existing libraries, switch the stack type to for example Average and then back to Layer to recover the disk space.
