SKYWATCHER AUTO-FOCUS SYSTEM FOR ALL TELESCOPES À NANTES

Bonjour à tous, I did not use this auto motorfocus: i only open the box to check the items ! all original items are included with the instructions Manual in original box: look at the pics ! A very simple and effective way to remotely control the focus of most telescopes. Has several brackets adaptable to refractor and reflector scopes from almost every maker. The electric motor with variable pitch is very reliable and provides a solid and uniform grip in order to get and maintain the adequate focus position. Uses a regular 9V rectangular prism battery. The price is the best on the market. This focuser is very easy to install and intuitive to use: look at the instructions manual on pics !
