Product Details

1. Background

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.

2. High Sensitivity

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. Note that a guide camera is not included with this and must be purchased separately.

3. Small But With High Precision

The miniGuideScope has a focal length of 130mm and a diameter of 30mm. The weight is only 111g (without included mounting bracket). 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.

4. Elegant Appearance

The miniGuideScope is exquisite in workmanship, elegant in style, and has a high face value, which can bring a stylish look to your guiding camera.

5. Focusing design

The front threaded focusing design with locking screw greatly simplifies the focusing mechanism without compromising accuracy. A number is engraved on the front focus ring to make it easy to remember the focus position. It can even be replaced with a short screw to permanently lock it in place once good focus is achieved.

6. Broadband AR Coated Achromatic Lens

Broadband anti-reflection coating on the achromatic lens assures sharp star images thus improving the tracking accuracy of the system.
