Thanks to a parabolic main mirror with a diameter of 130 mm, this instrument provides clear and detailed images of celestial objects for both beginners and experienced amateur astronomers. The telescope features diffraction-limited optics with a Strehl index of over 0.8, which guarantees the highest possible image quality for this class of instrument. The standard GP-prismatic rail ensures compatibility with most mounts, including GoTo systems with computer guidance, which opens up wide possibilities for modernization. The tube can be shifted and rotated in rings, which makes it easy to balance the instrument and install the eyepiece in a convenient position during observations. The kit already includes a solar filter, a lunar filter and two eyepieces, so the telescope is ready for full operation right out of the box. Thanks to The largely assembled design allows the instrument to be prepared for observations in just a few minutes.\u003c\/p\u003e\u003cp\u003e\u003cmeta charset=\"utf-8\" \/\u003e\u003c\/p\u003e\u003cp\u003e The lightweight single-spring alt-azimuth metal mount provides sufficient stability and stability during observations. For quick and correct orientation of the telescope, the mount base is equipped with a compass and a level. The telescope tube is fixed to the mount using mounting rings with a \"Dovetail\" mount, so it can be easily removed (both with and without rings) and rearranged to another, for example, equatorial mount for the convenience of astrophotography.\u003c\/p\u003e\u003cp\u003e \u003cb id=\"docs-internal-guid-305b2b4a-7fff-fa57-4368-4797094e10d7\"\u003eWhat space objects can be observed with this telescope:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e\u003cmeta charset=\"utf-8\" \/\u003e\u003c\/p\u003e\u003cp\u003e Sun: sunspots, solar flares, observation of solar eclipses, transits of planets across the Sun's disk (using the solar filter from the kit). \u003c\/p\u003e\u003cp\u003e\u003cb\u003e\u0026nbsp;\u003c\/b\u003e Moon: craters, mountain ranges, seas, valleys and other details of the lunar terrain (using the lunar filter from the kit). \u003c\/p\u003e\u003cp\u003e\u003cb\u003e\u0026nbsp;\u003c\/b\u003e Planets: the disk and cloud belts of Jupiter, the rings of Saturn and its moon Titan, the phases and polar caps of Mars, the phases of Venus, the disk of Uranus.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e \u003c\/strong\u003eDeep Sky objects (deep space): globular star clusters (e.g. M13 in Hercules), open star clusters (e.g. M45 Pleiades), bright nebulae (e.g. Orion Nebula M42), planetary nebulae (e.g. Ring Nebula M57), galaxies (e.g. Andromeda Galaxy M31).\u003c\/p\u003e\u003cp\u003e \u003cb id=\"docs-internal-guid-6123d76e-7fff-75bb-3a67-4382059cf7c6\"\u003eDesign features:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e\u003cmeta charset=\"utf-8\" \/\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e \u003cb id=\"docs-internal-guid-6123d76e-7fff-75bb-3a67-4382059cf7c6\"\u003eParabolic main mirror\u003c\/b\u003e - unlike spherical mirrors, the parabolic shape eliminates spherical aberration and provides a sharp image across the entire field of view. The mirror is made of a special grade of borosilicate glass, which makes this telescope a Diffraction limited optics class. The Strehl number \u003e 0.8 indicates that the telescope is practically free of aberrations. This is especially important at high magnifications when observing planets and lunar terrain. The user receives the clearest and most contrasted image without blurring at the edges.\u003c\/li\u003e\u003cli\u003e \u003cb id=\"docs-internal-guid-6123d76e-7fff-75bb-3a67-4382059cf7c6\"\u003eDiffraction-limited optics with Strehl above 0.8\u003c\/b\u003e — The Strehl index determines the quality of the optical system: a value of 0.8 and above means that the image quality is approaching the theoretical maximum for a given diameter.
