Sorry for the delay there. I keep getting different numbers for horizontal separation at different points along the length of the tube. It could be that the ocular end of the scope is significantly farther away from the camera lens than the objective end, and hence, it looks smaller. Or it could be measurably crooked (about a millimeter from one end to the other).
Anyhow, at the objective end (assuming an 18 mm opening) the horizontal separation of the scope center from the barrel center appears to be 15.6 mm or .61 inches
