Hi, I purchased SkySafari 6 Pro for my MacBook Pro with all the additional catalogs.
If I had to format my computer, can I install my SkySafari from the AppStore again, or do I have to pay for it again?
Thank you

No, you can just re-download it from the Mac App Store as long as you are signed into the same App Store account as you used for the purchase. For the in-app purchases, you will have to do a "Restore Purchases" from "Settings > In App Purchases".
Thank you
