Collimatable 1.25" diagonal?

There are several 2" diagonals out there, but anyone know of a 1.25" diag with collimation adjustments?

I'm not aware of any diagonals with built-in alignment adjustment mechanisms.

Many of the generic prism diagonals out there contain misaligned prisms, but they're usually fix-able by way of resetting one or more of the following: spring clip(s), barrel, collar. Beyond that, alignment might require some shimming. Of the nine different diagonals I've owned -- whether prism, mirror, .965-, 1.25-, & 2-inch models -- only one of them was misaligned when received (a Celestron prism diagonal). The aforementioned spring clip/barrel/collar "reset" was all I needed to do to realign the diagonal.

Do you have a misaligned diagonal, or are you just concerned about a future purchase?

Cheers & best wishes.
