[QUOTE="Capt RB, post: 1505057, member: 85987"] For those that are interested in the phenomena of the image moving due to the light being different. My data books have pointed out that the impact moves opposite of the position. Meaning sun low behind moves it up. low right = high left etc etc. How much does it move? The focal length of the scope the lense count, coatings, and quality are all factors. A longer focal length is easier to make which explains the old Enertl scopes. The video from Vortex gives you an idea how to figure it out. Set your rifle up and shoot 1 shot. Then leave it set up on the exact same aiming point. Then just record it for your data book. This explains alot of the benchrest records at 1k with the tight groups off the bullseye. In the video by Vortex you can see the cross hairs above the bull when the sun is high in the sky. If you held it on the bull you would shoot low and then scratch your head. [/QUOTE]
