The F♯ harmonic minor scale has 7 notes: F♯ – G♯ – A – B – C♯ – D – E♯. The harmonic minor is the natural minor with its 7th raised a half step. The gap of three frets between the ♭6 and the 7 gives it its exotic, classical sound, and the raised 7th makes the V chord major, so it pulls strongly back home.
F♯ and G♭ are the same pitch, so this page covers both names; the notes are spelled from F♯, the way the key is usually written. Compared with the F♯ major scale it has ♭3 (A instead of A♯), ♭6 (D instead of D♯).
The explorer above is set to F♯ harmonic minor: the whole neck is mapped, and you can zoom into any of its 7 positions, change the labels to degrees or fingers, and hear it up, down and in patterns.
