Your PA must be spot on as those stars at 1 minute are perfectly round and sharp
Plenty of fine nebulosity detail as well , I don’t know about pushing 3 minute subs on such a bright object like M8 ?? It may blow the core out too much ??
I reckon leave your subs at 1 minute or 90sec and just gather more subs If you can next time
Well done !! A really good unguided M8
