• You can now import images by simply dropping them from Finder onto a library window. This also works with folders.
• Empty libraries now have a drop zone for your images and folders. You can also click it to select them.
• Because Observatory is build around the concept of image libraries, an odd quirk since its first release has been that it wasn’t capable of opening a single image if you tried with Finder. You now can. It creates a temporary library with just that image. Use it to quickly inspect an image, its metadata, apply nondestructive adjustments, plate solve, overlay catalog data, and more.
• You can now stack images directly from Inbox! There’s no need to first move them to an album anymore. Observatory libraries are automatically upgraded to support this new feature.
• Stacks can now be moved or copied to another album using the corresponding menu item or by dragging them. Press the option (⌥) key to copy. To move a stack back to Inbox, choose “Image ▸ Remove From Album”.

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…” command 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.

Changed

• 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.

Observatory 1.0.5 November 12, 2016

New

• 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” commands. 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 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” commands. Press the Option key to access the previous “Add to New Album” and “Add to Album” commands. The corresponding commands 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.

Changed

• 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 commands 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 command 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” command has been renamed to just “Blog”.

Fixed

• 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.
• Browser: Resolved an image browser layout issue when switching between browser types.
• Sidebar: Improved the selection behavior in the library navigator, making it much easier to add folders, albums and smart albums.
• Sidebar: Resolved an issue where the sidebar was not always updated if there was a change to an album.
• Inspector: Fixed an issue that made it impossible to change the sensor 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.

Observatory 1.0.4 September 14, 2016

New

• 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.
• Browser: Badges are displayed for images that have notes or are marked as favorites.
• Virtual Observatory: Additional archives!
  • Wide-field Infrared Survey Explorer (WISE AllWISE Atlas). WISE is a 0.4 m NASA infrared-wavelength space telescope.

• Virtual Observatory: The ESO archive would under certain circumstances not be searched with the correct radius. This has been fixed.
• Virtual Observatory: Resolved an issue that prevented the air mass and observer name, if available, to be displayed in the inspector.
• Virtual Observatory: If an album is renamed in the sidebar, while the virtual observatory is active, this change is now reflected.
• Virtual Observatory: The exposure duration as displayed in the inspector for HLA images would sometimes contain extraneous zeros after its decimal separator.
• 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.

Observatory 1.0.3 August 3, 2016

New

• Spotlight: Observatory now includes Spotlight Importers for FITS and SBIG files. This means that, when choosing File ▸ Get Info for such files in 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 Finder itself!

Changed

• 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.
• Virtual Observatory: Search results are now displayed as they come in. You do not need to wait until the last archive returns its data anymore.

• Virtual Observatory: Fixed an issue which could result in duplicate searches to be submitted to the archives while they were still ongoing.
• Virtual Observatory: Changing the search radius will now start a new search.
• Virtual Observatory: Resolved an issue where under certain circumstances images would not be downloaded into the selected album.
• Preview: Virtual Observatory preview images sometimes were downloaded even when the preview pane or sidebar was collapsed. This has been fixed.
• Sidebar: The sidebar icon size is now adjusted when changing the corresponding preference.
• Histogram: Fixed an issue where selecting many images and a histogram preset would not set the black & white points correctly.
• Editor: Now images are correctly centered in the editor even on macOS Sierra.
• Editor: The editor zoom factor now is updated correctly when switching between assistant editors.
• Stack: Fixed an issue with layer offset handling.
• Crash: Resolved a potential crash upon quitting Observatory after using the stack inspector.

Observatory 1.0.2 June 8, 2016

New

• GPU Accelerated Computing: With the new “Compute Device” option in the General tab of Observatory’s Preferences window you can now instruct it to perform some intensive computations on the GPU instead of the CPU.
