Product Details

This expanding ring converts a T-2 female thread (M42x0.75) to an SCT male thread (2"x24tpi). 1mm optical path length.

Baader officially refers to this product as a Baader T-2 to 2" Thread Expanding Ring. However, we find this title confusing and prefer to call it a T2 to SCT ring. While the SCT thread is technically a 2" thread, most amateur astronomers usually mean the M48 thread (that is smaller than the SCT thread) found on most standard 2" eyepieces and accessories when they refer to a 2" thread.

Baader part number: T2-28a or 2958242
