This eliminates the settling and backlash that tend to occur on geared focusers, enabling a level of precision that rack-and-pinion systems cannot. The large drawtube resists twisting and flexing under heavy loads so even the biggest eyepieces and gear remain optically centered for improved views and images. In addition to this already impressive performance is a coarse and fine 10:1 dual focusing mechanism with 80mm of drawtube travel, a zero-shift focus lock to prevent the focus from slipping, and a focusing scale on the tube for precise focus repeatability. Threads on the eyepiece side enable the direct connection of various accessories such as diagonals and Click-Lock holders, plus T-mount adapters and rings.\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cdiv\u003e \u003cdiv\u003e In the Box \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e Alpine Astronomical Baader Diamond Steeltrack Crayford Focuser for Refractors \u003c\/div\u003e \u003c\/div\u003e \u003cli\u003eLimited 2-Year Warranty\u003c\/li\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cbr\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
