We have measured accurate celestial coordinates for over 4000 extragalactic objects primarily drawn from a list of MCG galaxies with no recently published accurate positions. We...

We have determined improved positions for 373 galaxies listed in the Southern Galaxy Catalogue of Corwin, de Vaucouleurs, and de Vaucouleurs (1985, Cat. VII/116) as having poor...

A homogeneous set of new measurements of nearly all (995 out of 1007) objects from the Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Cat. ) or in the first supplement...

The Imaging Science Subsystem (ISS) mounted on the Cassini spacecraft has taken a lot of images, which provides an important source of high-precision astrometry of some planets...

Phoebe is the only major satellite of Saturn with a retrograde orbit. The Cassini Imaging Science Subsystem (ISS) took a lot of Phoebe images between 2004 and 2017, but only a...

We present the astrometry of the five largest satellites of Uranus from observations spread over almost three decades with photographic plates and CCDs (mainly), taken at the...

We present the results of the observations of the Uranian satellites made with the 26-inch refractor at the Pulkovo Observatory in 2007-2016. During this time we got 17 normal...

Using the data observed in San Juan with the photoelectric Astrolabe Mark II of the Beijing Astronomical Observatory from February, 1992 through March, 1997, the radio stars...

Using the data observed with the Photoelectric Astrolabe Mark II (PA II) of the Beijing Astronomical Observatory during the period from Feb. 1992 to Oct. 1993 in San Juan of...

Photographic observations of XX century contained numerous and varied information about all objects and events of the Universe fixed on the astronegatives. The original and...

Catalogs of 145 astrometric positions of Uranus and 4 its moons U1-U4 and 62 positions of Neptune and Triton have been compiled with Tycho-2 as a reference frame from...

We present results of a study that combines photometry and astrometry for the open clusters vdB80, vdB85 and vdB130. We apply a model which analyses the proper motion...

A catalogue of equatorial coordinates and magnitudes for 2162 asteroids and 11 comets was compiled based on the results of processing of digitized photographic observations of...

A catalog of 1399 astrometric positions of Saturn's moons S2-S9 has been compiled with Tycho-2 as a reference frame from photographic observations obtained at the Main...

The compiled catalogue of 231044 stars was created from photographic and CCD observations of position catalogues observed by ground based telescopes. The catalogue destine for...

The file jovsat.dat contains 35 intersatellite positions of inner Jovian moons Thebe and Amalthea, derived from the observations made with the 2-m Zeiss RCC telescope of Terskol...

The Ilkhani zij compiled by Nasir al-Din al-Tusi and his colleagues in the first period of the astronomical activities (the 1260s and early 1270s) in the Maragha observatory...

Coordinates and identifications are presented for 726 Harvard Variable stars and suspected variables, discovered or studied by D. Hoffleit and announced in Harvard Bulletins...

In the course of other work I have obtained complete identifications for a problematic list of late-type stars by Dolidze (1975AbaOB..47....3D). The charts were used to make the...

The paper presents the results of position determination of minor planets carried out at the Skalmate Pleso Observatory in the year 2003. 108 CCD observations of 16 minor...
