"Keep in mind that these represent averaged, statistical errors. In actual field conditions, as seeing fluctuates, 175mm aperture will have its D/r0 in the 1.5-2.5 range during periods of better seeing, out-resolving both smaller and larger apertures. Even 600mm aperture is likely to have moments when D/r0 drops to ~2.5, or somewhat bellow; that is, however, very unlikely for 1.2m aperture, which remains inferior to 150-300mm apertures (approximately) resolution-wise."
To sie pokrywa z moim (malym) doswiadczeniem. Przez wiekszosc czasu newton 10'' pokazywal podobna ilosc szczegolow do 80ED ale byly krotkie, kilkusekundowe okresy kiedy obraz sie wyostrzal i ilosc szczegolow byla nieporownywalna do malego refraktora. Trzeba bylo na to nie raz bardzo dlugo czekac ale bylo warto
