F♯aug is symmetrical — its notes are evenly spaced — so Daug and B♭aug contain exactly the same notes. There are only four different-sounding augmented chords in all.
Move a single note and F♯aug becomes a different chord: lower C𝄪 to C♯ for F♯.
Where you’ll hear it
Notice the C𝄪 in F♯aug (F♯ A♯ C𝄪): each note of the chord takes its own letter (F–A–C), so the augmented 5th has to be written C𝄪 rather than D — the same key on a piano, spelled to fit the chord.
