Hi Tony I have an Istar 127mm f/8 achro lense set on its way , and if this 152mm is still for sale in about 3 weeks when mine arrives I will give you a report as to how good my 127mm is , same lense as your beauty but only 127mm .

.
From what I have gleaned off the net these Istars are world class .
Brian.

The scope is as new and about $1000 less than it would cost to get a new one. If you're seriously interested send me a pm with your address and I'll get a freight quote.
