Observatory 1.1.1

Updated Documentation

In case you didn’t look at Observatory’s documentation lately, you may want to choose Help ▸ Observatory Help or go straight to our website.

It is now much easier to navigate. It is Safari Reader friendly and you can add it to Safari’s Reading List for offline reading, or export it as a single PDF file.

We’ve also updated it with the enhancements that were introduced in Observatory 1.1 and 1.1.1.

Today we released Observatory 1.1.1. It modernizes the sidebar, allows you to edit an image version’s name directly in the image browser, tweaks things here and there and fixes several bugs. Read more about it in the release notes.

New Observatory 1.1.1 Sidebar

Ready for macOS High Sierra, but…

macOS High Sierra

Next week on September 25, Apple will release macOS High Sierra. Whereas macOS Sierra initially had many regressions, and we had to work hard to have Observatory ready in time for its public release, Observatory has always worked great on macOS High Sierra.

One thing to be aware of is that even on the latest 10.13 GM candidate (17A362a), Apple still has not fixed a regression in Quick Look. For Quick Look generators that are included in third-party applications, High Sierra’s Finder fails to display a full preview when requested, but defaults to a large thumbnail instead. This broken behavior happens for every such application we tested, including Observatory.

We have reported this issue to Apple many 10.13 betas ago, but as of today this regression in macOS High Sierra has not yet been fixed. For this reason, if you are using Observatory for previewing FITS, XISF and SBIG images in the Finder, we recommend not to upgrade to macOS High Sierra just yet.

Observatory 1.1 is here, and it is great

We quietly have been working on it for months, but today we finally can take the wraps off our latest and greatest update. Observatory 1.1 is a major update, focusing on improving the user experience, the ability to handle larger stacks and additional plugins.

Background Processing

Whenever you select an image or stack, or change layer adjustments in one of the previous versions of Observatory, it will block the application from accepting any user input while it loads and processes the images. This isn’t a big deal on fast systems when selecting a single image, or when processing a small stack, but on slower systems, those equipped with hard disks instead of SSDs, or when processing a large stack, the spinning beachball isn’t exactly a pleasant sight, and neither is the inability to stop the processing.

This all has changed in Observatory 1.1. It now remains responsive while loading, processing and stacking images. You can even edit an image version’s notes and other metadata during these tasks. Changing adjustments or stack settings will restart the processing. Selecting a different version may automatically stop it, depending on the selection.

There is a new “Stop Tasks” toolbar button and “File ▸ Stop Tasks…” menu item to gracefully stop image loading, processing and stacking. It also temporarily stops automatic library maintenance tasks.

The inspectors now display progress indicators when they cannot display the requested information just yet, and the one in the editor even provides a clue of how far the loading and processing has proceeded.

Larger Stacks

Observatory now uses less memory. Stacks can be larger, especially those without layer adjustments. As before, the system’s memory size will affect the maximum stack size and stacking performance.

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.

Another enhancement we made is that 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.

Acorn Plugins

Our FITS, XISF and SBIG plugins for Acorn that let you import these images at full bit depth straight into this powerful image editor are now included in Observatory itself. Choose the new “Observatory ▸ Install Extras…” menu item to install them.

Observatory Demo

It has been requested since we released Observatory 1.0, and today it has finally arrived, the Observatory Demo. You can download it from our website.

It is a demo, not a full trial, and does not include our Quick Look, Spotlight and Acorn plugins. These are all major features of Observatory, but we cannot effectively let these plugins “expire”, so they are not included. The demo will allow you to evaluate the many other features of Observatory though before purchasing.

Fixes, and more

We’ve made many more improvements throughout the application of course. See the release notes for the complete list.

We’ve also added new videos. One that demonstrates how calibration, stacking and plate solving works in Observatory, and another one that shows the Acorn plugins in action.
