Pat , do you mean the 8x56 GPO? Those have the AK prisms , the 8.5x50 use the SP prism I believe.Hola,
No not seriously but I have used them to observe the sky at night and they have been just fine. I use my GPO/Geco 8x50's with the AK prisms and mount them on a tripod if I want to do real astro or my Opticron MM4 77 scope.
