I am a Mac user and I bought originally TheSkyX + Camera Add On.
Very rapidly I bought the Dome Control Add On (just after that Rodolphe Pineau made a plugin for my dome set up), and then I bought the TPoint Add On.
I bought all these components within a period of 3 weeks.
I just realized that the total price ($ 1196) is not too far away from the price of the Universal Subscription ($ 1200).
I wonder if the Bisque company would accept to change my licence for a Universal Subscription ?
(I am ready of course to add $ 4) ;))))
