Optica b/c 3X Barlow (1.25).Posted By Charles Helms |
I picked up a Criterion Refractor and in the box was an Optica b/c 3X Barlow (1.25). I have seen the 2X Optica barlows before but never a 3x. I can find nothing about it online. There is a copy of Optica's 1978 line on the internet but nothing about a 3x Barlow. I did a side by side with my TV 2.5 (C8)and was pretty surprised. Anyone have any info on it or can point me in the right direction? I dont need another barlow but I have never had a 3x before thanks chuck
