Intermediate age open clusters: Collinder 110

Abstract

We present CCD BV photometry of the intermediate age open cluster Collinder 110, a nearby, scarcely populated, and poorly studied system. There is no literature information on the metallicity, so we tested several possibilities, and found a slight evidence of sub-solar abundances. Using the synthetic Colour - Magnitude Diagrams technique we estimate the following parameters: age between 1.1 and 1.5 Gyr, reddening 0.38 <~ E(B-V) <~ 0.45, distance modulus (m-M)o between 11.45 and 11.7 if the cluster metallicity is sub-solar.
