Woah! Amazing news!
I've long been contemplating a major ZWO purchase (AM5, ASIAir, guide camera, etc.) but the lack of support for my Sony A7iii has been the (only) thing holding me back. As a relative AP neophyte (currently using nothing more than a star tracker), I really want to take "baby steps" before jumping in even deeper with the rest of the ZWO ecosystem (eventually planning for a mono camera, filter wheel, auto-focuser).
I'll continue watching here for an update on the timing of 2.1 ... and free up some room on my credit card!
