NTT VI photometry in Terzan 5
We study the metal-rich bulge globular cluster Terzan 5 by means of VI colour-magnitude diagrams, with images obtained under exceptional seeing conditions (0.34"-0.50").... -
Liller 1
We carried out VRI and Gunn z observations of the obscured globular cluster Liller 1. The cluster is so reddened (A_V_=~9.0) that it is at the detection limit in V. The RGB in I... -
Globular Clusters Djorg 1 and Pal 6
We present NTT V,I observations of Palomar 6 and Djorgovski 1, two obscured loose clusters in crowded fields. We derive a reddening of E(B-V)=1.33+/-0.10, a distance... -
M3 photographic photometry
A new photographic colour-magnitude diagram for the Galactic globular cluster M 3 is presented. -
UV photometry of NGC 6397
The core of the nearby and very concentrated globular cluster NGC 6397 has been imaged through the f/96-F140W, f/48-F140W, f/96-F210M and f/48-F220W ultraviolet filters of the... -
The globular cluster NGC 6652

Hercules Messier 13 (M13) photometry
Ludendorff's catalog of the M13 globular cluster results from observations made with the 32.5cm refractor of Potsdam Observatory, one on 17 July 1900 (plate A), and the second... -
UBV HR Diagrams of Globular Clusters
UBV observations of over 37,000 stars have been compiled from the literature to yield 165 color-magnitude diagrams. There is a list of bibliographic references for each cluster... -
M68 variable star light curves
110 plates of the globular cluster M68, taken during 1951 to 1953 with the 24-inch reflector of the station of Lojano, have been the subject of a photometric investigation. Cone... -
Catalog of UBVRI Photometry of Globular Clusters
Photometric data directly obtained in UBVRI or converted to UBVRI magnitudes are tabulated. The data comprise approximately 4600 records from 56 individuals and contains data... -
Catalog of stars in M3
Catalog of 1571 stars contained in the globular cluster Messier 3, observed in 1905 at the Observatoire de Paris. Cone search capability for table I/278/catalog (Catalogue of... -
CFHT optical & NIR obs. of RR Lyrae in M15
Messier 15 (NGC 7078) is an old and metal-poor post core-collapse globular cluster that hosts a rich population of variable stars. We report new optical (gi) and near-infrared... -
Parameteres for 88 giant variable star candidates
We present the analysis of 510 light curves in V and I bands of 255 giant stars in the globular cluster NGC-3201. Our aim is to expand the sample of new types of variables... -
UBVRI phot. for galaxies, Gal. GCs & stars
From 1982 January to 1988 October, I used the 76-cm and 91-cm (30-inch and 36-inch) reflectors at McDonald Observatory in West Texas for UBV(RI)c observations of 239 galaxies,...
