TS-Optics Twist-Lock adapter from 2" to 1.25" with filter thread - clamped as if screwed! The Twist-Lock system allows perfect clamping on the optical axis. Tilting of accessories is prevented which means irritating problems with the common combination "safety groove and ring clamping" belong to the past. By rotating the upper ring, it embraces the eyepiece or adapter whilst travelling 15 mm. A gentle tightening is sufficient to achieve a secure connection. The TSTW2-1 fits in every 2" eyepiece reception and cannot tilt itself, because it doesn´t have a safety groove. The adapter has a telescope-sided 2" filter thread (M48x0.75) for screwing in 2" filters.
