I have not bought a program yet; I am not sure how all this will work. I have a main PC I do most work on, but I also have a Primalucelab Eagle LE that I use with my EQ6-R, Celestron 8 HD Edge and Tele Vue NP127is. I also have a Samsung Note 20 Ultra. It seems I would like to download to all these devices. Is there a program that can accommodate multiple devices?
