2" Eyepiece Clamp Four-in-One – with M56i / M60a / M68a / AP 2.7"a

As we do not have the 27TVPH lens at hand, we cannot say for sure. It will depend on how much space is inside the lens to accomodate the M56 and M68 threads. The M56 thread has a length of 7mm, while the M68 is 5mm. The 2.7" one is 6mm. This means that the length from the beginning of the M56 thread to the end of the 2.7" thread is 18mm. Please make sure to measure the available space to avoid the adapter making contact with the lens group.
