Collimation Screws and Locking Screws?

[austen4]

Hello I have seen pictures in the manual of what screw is which but this seems to be a error with me. The larger screw (collimation) I think should be a locking screw and the locking screw (smaller screw) should be the collimation screw because the large screw should just pull the mirror back onto the smaller screw which would collimate it depending on how far the screw is in/out? I NEED HELP PLEASE

Thanks in advance

Nope - you colimate it with the big screws - then when you've found the right position for the mirror lock it in place with the smaller screws - other wise you wouldn't know where to set the locking screws to pull it into collimation

When i bought my Skywatcher Heritage 130P i thought the very same. I thought the destruction manual made a mistake but nope............

Collimate with the big chubby screws and lock down with the smaller.
