Title:Blue Stragglers in Open clusters: A survey plan using 50BiN Abstract: We are going to carry out a open cluster photometric survey using the prototype of 50BiN (50 centimeter Binocular Network). All the open clusters in the visible sky from Delingha (in West-China) will be observed in two colors during the commissioning period before the switch to network mode. Blue stragglers identification will be carried out for this survey, and will be eventually cataloged.
