As a rule of thumb, any object that is inside the tube and in focus, such as the hair in Billy's 'scope, then it ON the focal plane. In other words, stuck on the grat or crosswire.

Now, billy, this is what yiu can do to correct yours, as a quick fix. |Unscrew the 4x small 8BA range/turret cover/index plate screws. GENTLY lift off the turret thumbscrew and underneath that, the complete diaphragm/graticle block assembly. Part fill a small egg cup with alcohol based cleaner/trichlorethylene or methylated spirit, sufficient to just cover the grat block and dunk the grat block in it for 15 mts or so. carefully slosh it around and hopefully the hair and other contaminants will fall off.

Blow the grat block clear with an air can but DO NOT, NEVER, EVER, NEVER touch it. Now assemble up and inspect.. Take apart, grease up the screw holes, smear of grease over where cover seals down, align clicker plunger, reassemble, test and screw down.
