I've been using Sky Safari Pro on iOS and Mac for a few major versions now, and SS7 for Mac seems to be way overdue. I'd be fine with running the iOS version on my M1 Mac, but it appears that it's not possible since it's not in the Mac App Store. If it's difficult to keep developing the Mac version, I'd ask that you please start making universal version that can run on both iOS and MacOS. I'm a huge fan and promoter of Sky Safari over the years, but I feel like the Mac is being left behind.
When Will SkySafari 7 Pro Be Available For M1 Macs? (Answer: Get It Now - Read On!)
