QHYCCD mini Guide Scope (MINIGS-WM)

In the era of high sensitivity and small pixel cameras, do you need a large and heavy guide scope? The answer is negative. Due to the high resolution (smaller pixels size) of the guide camera and the increase of the pixel density, the guide scope does not need to be a long focal length to sense the movement of the star image. As sensitivity is improved, it does not require a large aperture. As the focal length of the guide scope is shortened, the field of view increases, so that more guide stars will be within a fixed field of view. Based on these ideas, QHYCCD introduced the miniGuideScope.
