I replaced the focus assembly on my AP telescope with a two speed version. This focuser is a very solid and robust unit with baffles machined into the draw tube. The unit was fitted to AP130, AP155 and AP180 telescopes, and is sold by Astro-Physics as a part for those wishing to make their own tube assembly Sell for $200.00 including postage. Thanks Mark
