[QUOTE="CliffM, post: 624125, member: 11533"] I recently upgraded scopes from 60mm to 80mm. I don't know all the technical stuff but it seems that there is more to gain by larger objectives than by higher power. In silhouette matches a straight 27xLER lens is probably the most common. I usually don't go over 30x. Any higher and the image will get bigger but quality of it will start to degrade. Of course the very high end glass would make the most out of the lens size. There is a formula for figuring the the minimum size that a scope can resolve, and if I remember correctly many scopes will exceed that on the higher powers. Cliff [/QUOTE]
