I have a complete set, used 2 evenings, of the critically acclaimed TMB Monos 4mm,5mm,6mm,8mm,10mm. These are in as new condition include boxes and caps.I would really prefer a trade for some Denk II Binoviewers with all the current options available or will sell outright for $960.00 including shipping and handling. These are absolutely astonishing planetary and double star eyepieces. I already have a second set that I will keep.
