    (Astroprint, 2013) Andrievsky, Serhii M.; Molotov, I. E.; Fashchevsky, N. N.; Podlesnyak, S. V.; Zhukov, V. V.; Kouprianov, V. V.; Kashuba, S. G.; Kashuba, V. I.; Mel’nichenko, V. F.; Gorbanev, Juri M.; Андрієвський, Сергій Михайлович; Андриевский, Сергей Михайлович
    ABSTRACT. A new automatic telescope, a 800-millimeter main mirror catadioptric anastigmatic aplanat, was constructed by specialists of Odessa National University Astronomical observatory (Ukraine) in cooperation with their colleagues from the ISON project (Russia), and was recently put into operation. The telescope is mounted at Mayaki station in suburb of Odessa. It is equipped with a focal corrector and a professional CCD camera. The telescope is used now for observations of geostationary objects, asteroids, and comets. In addition, this telescope can be used for the high precision photometric observations of faint objects up to 20m.

    (Pleiades Publishing, Inc., 2006) Gorbanev, Yuriy M.; Golubaev, Aleksandr V.; Zhukov, V. V.; Knyaz’kova, Еlena F.; Kimakovskiy, Sergey R.; Kimakovskaya, Irina I.; Podlesnyak, S. V.; Sarest, Leonid A.; Stogneeva, Irina A.; Shestopalov, Vasiliy A.
    A review of TV and telescopic methods of meteor observations and of the problems of meteor astronomy addressed using these methods is presented. A meteor patrol developed at the Astronomical Observatory of Odessa National University and based on a Schmidt telescope and a TV detector is described. The meteor patrol allows meteor events to be recorded with a time resolution of 0.04 s. The investigated characteristics of the patrol are reported, and some aspects of the methods of observations and reduction employed are considered. The results of observations made during the period 2003–2004 are reported. A total of 368 meteors were recorded on 1093 individual frames during a total patrol time of 679 hours within a 36′×48′ field of view. The statistical data for meteor observations are reported, and classification of meteor images is presented. The specific features of some recorded meteor events are analyzed.

    Monitoring of space objects using Odessa Observatory network of telescope
    (2019) Andrievsky, Serhii M.; Bazyey, N. V.; Zhukov, V. V.; Koshkin, Nikolay I.; Kashuba, V. I.; Kashuba, S. V.; Gorbanev, Yuriy M.; Sukhov, P. P.; Podlesnyak, S. V.; Udovichenko, S. N.; Keir, L.

    In this paper we are presenting optical telescopes of Astronomical Observatory of I. I. Mechnikov Odessa National University. We are describing technical characteristics and scientific program for each telescope. Here we also present a description of the tools with which the unique collections of astroplates were obtained under the program “The Sky Service”. Odessa Observatory (46°.28 N, 30°.45 E, altitude 64 m, observation code 086) it has several observational stations. Among them: Mayaki (46.39° N, 30°.27 E, altitude 25 m, observation code 583) and Kryzhanovka (46°.37 N, 30°.48 E, altitude 40 m, observation code A85). Both stations have a good geographical location, as well as good astroclimate (up to 200 clear nights or part of the night). Telescopes are equipped with modern CCDs and photometric light detectors. Odessa Observatory has its own mechanical and optical workshops that are used for construction the new telescopes and manufacture and repair other astronomical equipment.

    New wide-field telescope with a mirror diameter of 600 mm for the telescope network of the Odessa Observatory
    (Одеський національний університет імені І. І. Мечникова, 2020) Fashchevsky, N. N.; Podlesnyak, S. V.; Bondarenko, Yu. N.; Andrievsky, S. M.; Romanyuk, Ya. O.
    Optical scheme of the new wide-field telescope of the telescope network of Odessa Observatory is described.The telescope optical layout is designed as a mirror-lens system with a Ross-type two-lens corrector and a hyperbolic primary mirror with diameter of 600 mm. The prime focus corrector is capable of imaging a field of 2 degrees, the rootmean-square radius of the diffraction spot is about 4.5 m, which is 2.5 times larger than that of the diffraction-limited spot (Airy disk).

    Spherical primary mirror in telescopes with complex (multi-element) optical designs
    (Одеський національний університет імені І. І. Мечникова, 2021) Podlesnyak, S. V.; Fashchevsky, N. N.; Bondarenko, Yu. N.; Andrievsky, Serhii M.; Андрієвський, Сергій Михайлович; Андриевский, Сергей Михайлович
    An optical design for telescope with spherical primary mirror, planoidal surface and two-lens corrector is discussed. The spherical mirror has an aperture ratio 1/2.69. After reflection from the spherical mirror, the wave front falls on a planoidal surface and “forms” the reflected wave front from a virtual mirror with e2 = 1.576. After passing the two-lens corrector, the light is collected in the focal plane. A dot diagram in the focal plane shows that all three-order aberrations are successfully corrected. The effective field of view is 2 degrees. The aperture ratio is 1/2.28.

    Techniques for Positional Measurements of Telescopic Meteor TV Images
    (Pleiades Publishing, Inc., 2008) Gorbanev, Yuriy M.; Golubaev, Aleksandr V.; Zhukov, V. V.; Kimakovskaya, Irina I.; Kimakovskiy, Sergey R.; Knyaz’kova, Еlena F.; Podlesnyak, S. V.; Sarest, Leonid A.; Stogneeva, Irina A.; Shestopalov, Vasiliy A.
    We present the results of our positional reduction of the observational material obtained using a meteor patrol based on a Schmidt telescope and a TV CCD detector. More that 1000 telescopic meteors were recorded in three years of meteor patrolling. Techniques for the cataloging and positional reduction of 3050 TV images with meteor trails are described. We have developed a technique for measuring the images of reference stars to determine the rectangular coordinates in the image frame. We discuss the achieved accuracy of determining the equatorial coordinates of reference and check stars by Turner’s method (of the order of a few arcseconds). We have developed software that allows the rectangular coordinates of meteor trajectory points to be determined after the meteor image reduction. These coordinates are used to determine the equatorial coordinates of the poles of the great circles of meteor trajectories (the angular length is not less than 15′ with an accuracy of at least 4′. We consider the possibility of using Stanyukovich’s method to determine the equatorial coordinates of radiants for non-basis meteor observations. The accuracy of determining the radiant coordinates has been estimated to be 4′–5′. Prospects for obtaining the kinematic characteristics of meteor particles are discussed.

    This paper presents the results obtained using a Schmidt telescope (with primary mirror diameter 271.25 mm; correcting plate diameter 219.2 mm; effective focal length 0.44 m and focal ratio 1/2) in different configurations to conduct television meteor patrol, as well as comet and asteroid observations.
