The prominent, large dust lanes on the disk of M31 are NOT meant here, of course.
This article talks about the filaments that are seen very close (10') to the M31 core on photographs. Can those bulge filaments be seen visually by DSOs ? How ? Amazingly this turns out to be an observation feasible under middle-/low-class skies (21.25mag/sq.arcsec) as well, probably also with much smaller telescopes than 20"... I know M31 is a bit ON the beaten track, but so what !?
FYI: you may have noticed another thread of mine on the more general topic of experience w/field sweeping as well.
Thanks for comments.
