Practical application of Ka seglin telescope

Large-scale terminal equipment can be placed at the focal point of seglin telescope, which does not block the light and is convenient for observation. For telescopes with main focus system, Ka-seglin system and folding axis system, the relative aperture of Ka-seglin telescope is medium, which is suitable for taking large-scale photos with medium optical power. Generally, the main work carried out here includes spectroscopic observation of large spectrometer, direct photography and image intensifier photography, photoelectric photometry and infrared observation.

This design is very common in telescopes provided by manufacturers to consumers, because spherical optical surfaces are not only easier to make than refractive telescopes with long focal length. Although this kind of telescope is more expensive than the reflective telescope with the same caliber, it is easy to carry within the designed caliber because of its compact optical design, which makes it more popular among serious astronomy enthusiasts and becomes the mainstream amateur high-end astronomical observation instrument at present. The high focal length ratio means that it is different from its predecessor, Schmidt Star Detector. It is not a wide-angle telescope, but its narrow field of view is very suitable for observing planets and deep space objects.
