CCD photometry of the M87 jet in the Thuan-Gunn r and g filters is presented. Accurate elliptical models of the underlying stellar emission were subtracted from...

We present new BV photometry for 6564 stars in the field of the globular cluster NGC 6366, using a wide field CCD camera at the prime focus of the Isaac Newton...

We report the results of CCD V and R photometry of the RRstars known in NGC4147. The periodicities of most variables are revised and new ephemerides are...

ABSTRACT: B, V, R, and I CCD frames were obtained for the Southern Galaxies NGC 5757, and IC 1091. The frames were analysed to derive standard photometric and...

CCD imaging of low-luminosity radio galaxies to detect the optical counterparts of radio jets is described in terms of the surface-photometry procedure and the...

Results of CCD photometry of the three low-luminosity radio galaxies which contain jets at the kpc scale: B2 0836 + 29, B2 2116 + 26, and B2 2236 + 35 are...

In this paper we present the Johnson-Cousins UBVR CCD photometry of the stars in King 2, an old open cluster towards the galactic anticenter. We have obtained...

This paper presents the Johnson-Cousins UBVR CCD photometry of two old rich open clusters toward the galactic anticenter: King 11 and Be 42. Included are the...

BVRI CCD-based and near-IR (J) imaging, together with unfiltered photometry of the hot subdwarf B star PG 0856+121, are reported. Two close, faint, red, point...
