Nothing wrong with mine as well  .

Hi Brian,
Thanks for that - you are getting good performance with the 9mm GSO in your Tak, and I am happy with it in my Mak. They must have something going for them.
I remember when S&T did their evaluation of the then available Plossls years ago, and they rated them against four or five criteria. Televue were the best against each criterion, but most of the others scored reasonably well too - there weren't any they rated as poor.
Regards,
Renato
