ngc 206: star cloud in M31

Experience looking for these dim objects really seems to help! I always had to struggle to detect this slightly brighter spot in the Andromeda galaxy in a 10" reflector. Now instead I can pretty much immediately see it (my site is reasonably dark, about 5.3 or so limiting magnitude). And last night I even saw it - with averted vision - in my 4" Traveler!
What's your experience sighting this stellar cloud?
By the way, the emission nebula NGC 604 in M33 is smaller but much easier to see.

Antonio,
I think you pegged it your observation that experience really does help in detecting what the "Observer's Guide" refers to as a "stellar association." The Guide states it's easy in an 8"/10" scope at 125X in the SE arm of M31. The Guide further states it is an elongated "2:1", and "fades off into the spiral arm".
