[QUOTE="coyotezapper, post: 1159697, member: 20438"] For a scope to be clear in low light it needs a few things. First is good glass with good coatings among other things. Price is a good indicator to tell whether or not the glass and coatings are good in most cases. There is a reason why S&B scopes are so expensive. The second thing needed is proper exit pupil. For example on the Razor 5-20x50 the exit pupil is 2.5mm when set on 20 power. Exit pupil matters most when shooting at twilight. That being said, at 20 power there will be a time in low light situations when the exit pupil is too small. Remedy? Turn magnification down. 50/5= 10mm exit pupil at 5 power. You will not always have a good sight picture at high power in low light. All of my Vortex HS LR and HS-T's have issues with light scatter in afternoon/evening sun. Another example of getting what you pay for. Best glass for the money? Leupold. My VX3 8.5-20x50 is as bright as my NXS 5.5-22x50 and my VX6 3-18X44 ( This is not a fair comparison because the resolution is always better in smaller diameter objectives when all other things are equal ) glass is even better. Mark 6 and Mark 8 glass is as good as anyones but once again it is pricy. [/QUOTE]
