Autofocuser 3

Based on your feedback and our experience with AF1/AF2, we have developed an upgraded version of our autofocuser. It is based on newer technology, boasting a stealth drive feature for minimal noise and vibration. Apart from the smoother motion, it also provides more accurate movement with microstepping down to 1/256. Enclosure was also optimized for easier assembly, but of course retained backward compatibility with every existing adapter. AF3 is also ASCOM/INDI compatible, just like AF1 and AF2.
