Thanks. I think the illumination as with everything else is exactly the same on both scopes. I’d have stuck with Kahles for the rest of my life, but I looked through an S&B which seem to suit my eyes better hence whole sale swap to S&B.Great scopes. I have read that many reckon the illumination is actually better on the older Helia 5 model.
Good luck with the sale, very underrated scopes.
