Abstract: Star clusters are excellent tools for teaching several aspects of stellar evolution due to the fact that they are groups of stars with varying mass, but all the same distance, interstellar reddening, age, and metallicity. Therefore, the effects of age and metallicity on determining evolutionary properties of populations of stars can be investigated by studying different star clusters. We have developed an interactive web app that can be used to analyse both user-supplied and archival photometric data from various all-sky surveys (Gaia, APASS, 2MASS, WISE), to remove field stars and isolate cluster stars, and to fit isochrone models and determine a wide range of cluster properties (age, metallicity, distance, reddening, number of stars, etc). In this workshop, we will describe the various steps of the analysis and provide an opportunity for participants to select clusters to analyse with Skynet's Cluster Astromancer tool (https://astromancer.skynet.unc.edu/cluster).
