Have just been handed a pair of old 8x30 Jenoptems with serious double image. Having correcded this on the front concentric rings I find that I have a twisted image. the l/h eye is very slightly clockwise and r/h eye is way out anticlockwise. They are in very good condition with no aparent damage from being droped. The twist was there before I adjusted the double image. Any help from you experienced guys woul be appreceated.
