Quick Look

Quick Look lets you view a file’s contents by selecting it in the Finder and then pressing the spacebar. There’s no need to wait for the file to open in an application. Although macOS supports many types of images, the formats typically used for astronomy are not. Observatory therefore provides Quick Look generators for the following image formats:

To zoom in on an image when the Quick Look window is open, hold down the Option key. If you have PixInsight installed then there’s an Open with PixInsight button towards the top of the window, which when clicked will open the image in PixInsight.

As can be seen in the above screenshot, the plugins also generate image thumbnails for the Finder windows. In addition they are used in its Cover Flow view and for the Finder’s Get Info window. They even appear in the Dialog for opening files (instead of generic icons), in any application. In these Dialogs you can also view a file’s contents up-close by pressing spacebar.
