miniGuideScope A high-value miniature guide lens In the era of high-sensitivity and small-pixel cameras, large and heavy guide lenses are still needed? the answer is negative. Due to the reduction of the pixels of the guide star camera and the increase of the pixel density, the telescopes that do not require too long focal lengths can well sense the movement of the star points; as the sensitivity increases, they do not need large apertures. Telescopes, especially because the focal length is shortened, the field of view will increase, so that there are more bright stars in the field of view. Based on the above-mentioned thinking, QHYCCD has introduced a guide star telescope that perfectly matches the famous QHY5L-II planetary/guide star camera: the QHY mini guide star mirror. The telescope's design is seamless with QHY5L-II. And using the front screw focusing design with locking screws greatly simplifies the focusing mechanism without losing accuracy. A number is engraved on the front focusing ring for easy memory of the focus position. It can even be replaced with a short screw to permanently lock the focus once and for all. The mini guide lens has a focal length of 130mm and a diameter of 30mm. The weight is only 120g. Using broadband anti-reflection achromatic lens, the imaging quality is more sharp than that of telephoto industrial lens. The sharp star point is conducive to feedback error and the accuracy of guide star is improved. The Mini Guide Star Mirror is fine workmanship, elegant in shape, and has a high value of beauty. It can bring a stylish atmosphere to your camera.Note: Cameras without the QHY5II in the pictureMini guide lens spec sheetcaliber30mmfocal length130mmCoke ratio1:4.3Optical system typeDouble gluing lens groupFocusing systemFront type screw focusFocus lockHaveCamera interfaceC mouthCompatible camera modelsQHY5L-II-C QHY5L-II-M QHY5R-II-C QHY5P-II-C QHY5P-II-MInternal tube extinction paintCoatingWeight (only telescope)120gTelescope connectorOptional universal finder adapterGuide tube barrel diameter (rear, non-focus tube)31.6mm
