IMPORTANT NOTE:
Please note that the small male SCT thread length is 7mm. While this will be adequate for most SCT diagonals, please make sure that the female SCT thread on your diagonal does not exceed 7mm. A few diagonals, most notably William Optics' SCT diagonals, have a female thread length longer than 7mm. Such diagonals will not lock on this adapter without the use of an additional o-ring such as the item at this link (not included).
