A sign for Italy's Prime Meridian Italy's Prime Meridian, defined in 1871, is situated in a brick tower at the top of Monte Mario - Rome's highest hill. The Italian Government chose the site to be the point of passage for the Prime Meridian on Septe

Berkeley 59 is a nearby ($\sim$1 kpc) young cluster associated with the Sh2-171 H{\sc ii} region. We present deep optical observations of the central $\sim$2.5$\times$2.5 pc$^2$ area of the cluster, obtained with the 3.58-m Telescopio Nazionale Galil

V725 Sgr is a rather peculiar variable that showed a period increase during part of the twentieth century. Its behavior is attributed to rapid stellar evolution. V725 Sgr was monitored in V, R, I and J, H, K with the REM telescope, on La Silla, from

We have previously established, from a carbon star survey, that the Local Group dwarf irregular galaxy NGC 6822 is much larger than its central bright core. Four MegaCam fields are acquired to survey a 2$^\circ\times$ 2$^\circ$ area centred on NGC 68

We employ the CFH12K mosaic to identify carbon stars, using the R, I, CN, and TiO photometric technique, in a 2240 arcmin2 area, ranging from 17 to 30 kpc of the southwest disk of M31, barely reaching the edge of the observed H I disk. We found 945 C

We matched spectroscopically identified C stars (from low-resolution objective prism surveys) in the Magellanic Clouds with Two Micron All Sky Survey (2MASS) sources. We confirm that C stars show a large spread in absolute magnitudes, even in the Ks

Using the CFH12K camera, we apply the four band photometric technique to identify 904 carbon stars in an area 28' x 42' centered on NGC 6822. A few C stars, outside of this area were also discovered with the Las Campanas Swope Telescope. The NGC 6822

We present the results of a survey made using 35 15' × 15' CCD fields, covering a total area of 2 deg2. These targets probe the southwestern periphery of the Large Magellanic Cloud and, for comparison, a few fields in the southeastern outskirts. V a

Hubble Space Telescope F606W observations to 26th magnitude are used to investigate the stellar distribution in the center of the Ursa Minor dwarf spheroidal galaxy. The central surface density is found to be low, less than 700 stars arcmin-2, with n

We present BV CCD photometry of a field of blue stars in the midwest of the Large Magellanic Cloud (LMC) located nearly 3? from its center. This stellar population, first noted by M. Pierre (1987), is found to consist of stars of all ages greater tha
