On the Optics
Planet web site page for the #788045 Elite 20-60x80 Spotting Scope
..., in the photo ... on the left side of the scope there appears to be a small knob that seems to me would be for a locking center ring that would allow mulitple viewing angels. But, the Bushnell
website does not mention a locking center ring that allows for rotation.
Am I correct on this?
