Mark,
I recommend you read an article by Craig Stark ( original developer of PHD guiding software) called “ Sampling Myths” circa 2010
Puts it all into perspective plus an attached image comparison
A bit technical but even an old dumbo like me can sort of understand it
Cheers
Martin
PS: I’ll take a 6” , 8” or 10” newt over an 80mm or 100mm refractor any day , no disrespect to anyone at all , it’s how deep you want to explore into an object and get the most resolution out of , that’s my challenge
