This expanding ring converts a T-2 male thread (M42x0.75) to an SCT male thread (2"x24tpi). 1mm optical path length. Has a female T/T2 thread on one side and a male SCT thread on the other.
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.
