Recently got a JMI RB-16 16" f4.5 'reverse binoculars' (big!!!) and have a question:
When I have the OTA's aligned as per the instructions and have a star merged in the center of my view the stars outboard from center are doubled and the farther from center they are the wider the separation. Put another way as I sweep the star side to side from center the two images separate and move farther and farther apart from each other. I am using a pair of 19mm Panoptics.
Any idea what I've done wrong? I had an RB-66 a while back and it didn't do this.
Thanks in advance for your input.
PS: Is this the right forum in which to ask this question?
