It's perfectly fine to mention Nebulosity here. Craig has long been a pillar of this community and deserves nothing but the best. If you decide Nebulosity is best for you, we are just happy you found something to suit your needs and get deeper into the hobby. We compete with nobody...
This depends on your needs. SGPro moves a lot closer to true automation, but does not come with any image processing software. PixInsight is a very nice companion to SGPro.
It does. The SGPro trial has full, unrestricted access to the main application and all of its addons (Mosaic and framing wizard, Notification wizard)
The MFW is actually $39.
Not currently. SGPro takes data from cameras and writes it to files unaltered (except with DSLRs). The QHY10 is, for unknown reasons, the ONLY camera that returns data in a portrait orientation. Several other folks gave complained about this as well... this should be taken up with QHY.
