Due to the reduction of the pixels of the guide star camera and the increase of the pixel density, the telescope with too long focal length can sense the movement of the star point well; as the sensitivity increases, there is no need for a large-caliber telescope. The telescope is now available, especially due to the shortened focal length, so that more bright stars can be guided in the field of view. Based on the above-mentioned ideas, QHYCCD has launched a guide telescope that is perfectly compatible with the famous QHY5L-II planetary/guide star camera: QHY mini guide star mirror. The design of the telescope is integrated with QHY5L-II. And adopts the front threaded focusing design with locking screw, which greatly simplifies the focusing mechanism without losing accuracy. Numbers are engraved on the front focusing ring to facilitate 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 120 grams. Using broadband anti-reflection coating achromatic lens, the image quality is sharper than when using a telephoto industrial lens. The sharp star point is conducive to feedback errors and improves the accuracy of the guiding star. The mini guide mirror is exquisite in workmanship, elegant in shape, and high in appearance, which can bring a stylish atmosphere to your star device.
