Color--Magnitude Diagrams and Luminosity Functions down to the Hydrogen Burning Limit. III. A Preliminary HST Study of NGC6791
I. R. King, L. R. Bedin, G. Piotto +3
Using HST ACS/WFC images, we derive the color--magnitude diagram of the old, metal-rich open cluster NGC 6791 to nearly 29th magnitude in V, which is the neighborhood of the hydrog…

Star-Cluster Astrometry with Ground-Based Wide Field Imagers
L. R. Bedin, J. Anderson, G. Piotto +2
We show the astrometric potential of the Wide Field Imager at the focus of the MPI-ESO 2.2m Telescope. Currently, we are able to measure the position of a well-exposed star with a…
