Hi,
I've been looking for a link to download the Acorn plugin without success
Please help !
Thanks
In Observatory, open the User Guide with Help ▸ Observatory Help. Select the "Acorn Plugin" section towards the bottom of the Table of Contents. This article describes how to install it and links to the plugin.
OK it worked. Thank you.
Astonishingly Acorn 7 cannot open a .fits file directly !
