QHY 30mm f/4.3 MiniGuidescope - 100062 Antlia Dual & Tri-Band Filters High precision encoder with realtimeWhen the pixels of a guide camera becomes small and QE becomes high, you may not need a big guide scope; smaller pixels can detect the guide error in a shorter focal length. Furthermore, when the focal length is reduced, the FOV becomes larger, so it is easier to find bright guide stars. The QHYCCD miniGuideScope is based on just this idea. The miniGuideScope is a 30mm f 4. 3 (130mm FL) ultra small telescope. It has no complex focal adjust system.
