FIELD: astronomical instrument engineering. SUBSTANCE: the invention is aimed at creation of a portable telescope consisting of several components provided with a quick-detachable joint. Detachable tube with a measuring eyepiece for angular measurements at an altazimuth adjustment of the telescope, a detachable tube astrograph for photography at a parallactic adjustment of the telescope, body accommodating the vertical axis shaft if the telescope is adjusted in an altazimuth mounting, or the hour axis shaft at a parallactic mounting, which is provided with a worm gearing, whose worm is provided with a control wheel made in the form of a worm gear-wheel with a handle providing for slow manual rotation of the vertical axis shaft in azimuth, as well as for automatic rotation of the hour axis at a frequency-one revolution per side-real day at a parallactic adjustment of the telescope make up the telescope components. The components also comprise a supporting part with three supports adjustable in height. The horizontal axis shaft is attached to the end of the vertical axis shaft for rotation, the detachable telescope tube may be rigidly fastened at the end of the shaft with the aid of a quick-detachable joint. The horizontal axis shaft is provided with a mechanism providing for a slow turn of the tube in the direction to the zenith at an altazimuth mounting and for a slow rotation of the declination axis with the tube at a parallactic adjustment of the telescope. The telescope is provided with a detachable clock mechanism installed on the side wall of the body above the control wheel and including a worm gear-wheel, DC micromotor, reduction gear and a worm. The shafts of the vertical and horizontal axes are provided with vernier dials calibrated in degrees, and the hour axis shaft is provided with a vernier dial calibrated in hours and minutes. The telescope is provided with a means for leveling, in which a liquid agent is used providing for aligning of the horizontal axis shaft perpendicularly to the horizon, and the tube sighting line exactly in the direction to the zenith. The telescope is provided with a detachable gnomon, with the aid of which the aligning of the hour axis and the declination axis exactly in the meridian plane is provided. EFFECT: enhanced convenience in transportation, readjustment from the altazimuth mounting to the parallactic one and vice versa, enhanced convenience in use. 35 cl |
