The QHY Mini Guidescope is now changing colour to black. Therefore we are clearing the original, silver model.
The QHY mini GuideScope is exquisite in workmanship and style. Weight (telescope only) is only 111 grams.
In the era of high sensitivity and small pixel cameras, a a large and heavy guide scope is not really necessary, particularly for small imaging scopes.
The high resolution (smaller pixels size) of modern guide cameras and the increase in pixel density, means guide scopes no longer need to be a long focal length to sense the movement of the star image. As sensitivity is improved, it does also 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.
QHYCCD introduced the miniGuideScope to match the famous QHY5L-II planetary/guide camera. However, it is compatible with all of the QHY5II Series cameras and the QHY5III Series cameras. By using a back-illuminated Series III cameras, the sensitivity and accuracy of the system is improved even more
The miniGuideScope has a focal length of 130mm and a diameter of 30mm. The weight is only 111g. The use of broadband anti-reflection coating on the achromatic lens assures image quality that is sharper then the use of a telephoto industrial lens. Sharper star images provide better feedback regarding tracking error, so the accuracy of the system is improved even more.
