I have a TOA130 and there is no way under the sun that I would attempt to mess with the collimating screws. These scopes require specialist equipment for collimation. As far as I know only Takahashi themselves and Takahashi America or TNR are the only people geared up to collimate these scopes. You will note that you can buy a Takahashi collimating scope, which is supposed to be for collimating their refractors, but I believe it will only work with the FS series of refractors, I have been told by the guys at TNR that these collimating scopes do NOT work with the TOA series. As Greg has said, the front cell which consists of the 3 elements is a separate entity to the rest of the ota, and is housed in the part that has come loose, just tighten it up, and I am sure you will find it will be ok. Any doubts though, contact the guys at Takahashi America, they are excellent to deal with. Art Ciampi and Fred are the two in question. They can be contacted via the Takahashi uncensored Yahoo user group.
