    Help! Coatings on Victory SF being... weird?

    What happens with the color reporduction when you look at colored obects with the separe binocular tubes? I ask it since what you see are reflection colors on the objective lenses and that does not necessarily mean that your image shows a similar color shift. Gijs van Ginkel
