This may not be entirely true, at least for brighter objects and for Sony sensors. Here is my attempt at 120s subs from two years ago from near Brisbane's CBD; I reckon I could easily get away with much shorter 3nm subs on this target:

And of course narrowband subs could be even shorter (but not optimal) on a faster scope and with less arcseconds per pixel
