When you add it to the External Editor list in Preferences, you can select a photo in Lightroom, R-click and choose [Edit-In Astra Image], Lightroom then creates a new file (type depends on your Preference choices) and opens it in Astra Image. [Save] from Astra Image and the photo will automatically be shown in the Lightroom catalog.
