Ever since Baader Planetarium first introduced their superb Clicklock clampimg system we have hounded them to produce a premium Clicklock version of their 2"/1.25" reducer. The new T2-15B is the result, and it delivers on every count. As with the standard T2-15, the new T2-15B Clicklock reducer is produced to close tolerances, is hard anodized, and incorporates 2" (M48) filter threads as well as internal T-threads (M42) for attaching the T2-15B to other Baader accessories such as diagonals.
The clicklock system securely locks your 1.25" eyepieces with a fierce non-marring grip, with just a quick 20degree twist of the knurled outer ring. A knurled Clamp Lever is also provided for added convenience, and to give a quick visual indication of clamp position. The innovative clicklock system uses internal hardened camming elements that securely lock eyepieces into the barrel, while precisely aligning and squaring their optical axis. Simpler low cost holders employ a threaded ring and simple ferrule style collet that does not guarantee alignment or squareness.
