Yes, it is free. Just it will not be on PixInsight's server anymore. And, to be true, saying that it is a limited edition is not close to reality. It was, when first released. The Standard edition shared the same interface, and it just included more processes. Right now, the PixInsight application has little of this first version... the idea behind the interface, but the code is all new, way too improved and refined, and there many things that we had not dreamed of at that time (image containers, history of the images, installable modules... uffff.... almost and end-less list). This is why LE is obsolete. It does not reflect what is happening right now with the main application.
