A couple months back I sustained an eye damage. I've been playing with the doctors for a couple of months and have another appointment here in about 30 days but I'm not sure and they're not sure if there's any real repair to this. I've lost the ability to see my targets clearly at 100 yards I can still shoot 50 with quite a bit of strain. My desire for a 50 Power Scope is now becoming a, I think, necessity. However, I'm looking at the NiKKo stirling and the falcon. I know that the Nikko will get a little foggy at 50 power but I don't need it to 50. probably up only the 40 and the price is right at around 800. I'm looking for any advice and experience on the Nikko and others but, being retired and on Social Security with a budget, $800 is a lot better than 11 and 13 and 15 and 18 and 19. Thanks in advance.
