Every morning my telescope lens is covered in fine hair like stuff. It sort of looks like super fine 1mm long fiberglass strands. I thought it might be flocking material, but my guidescope and edge 8 don’t have flocking but they get it too. It’s literally every night and if i don’t clean it, it continues to build up. 

any ideas?

Is that an Askar? My Askar does the same thing due to the flocking material inside the dew shield. It seems to be worse if I extend or retract the dew shield with the lens cap still on, due to the suction it creates. It does seem to blow of easily with a bulb blower.

Second on Chris' comment above. My Askar FRA500 does the same thing. Seems to be getting better as the new wears off.
