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.

Product description TS Optics dimmable LED Flashlight with red and white light The energy-saving LED torch is an essential piece of equipment for all amateur astronomers. The brightness is fully dimmable with a rotary knob, from a dim glow which does not dazzle to maximal illumination for searching items on the ground. And if red light is not sufficient anymore, you simply switch to white light. Very practical is the carrying cord. With it, the flashlight has its own place during the night. Power consumption is very low. A test with the flashlight switched on showed that it began getting dimmer not until after about the fourth day. Supplied is a commercially available 9-volt battery which is simply replaced if needed. Delivery contents LED flashlight with carrying cord
