Fotometría ``Python" del cúmulo abierto NGC 6834

Open clusters are ideal objects for studying intermediate and massive stars. In particular, NGC 6834 is a well-studied cluster with fundamental parameters that currently present a large dispersion. In order to better estimate these parameters, we have worked with images of the cluster adquired at the Gemini North Observatory, and processed with tools based on the PYTHON language, such as DRAGONS for pre- reduction and PHOTUTILS for photometry. We constructed color-color and color-magnitude diagrams that allowed us to adopt a distance of 3.33 ± 0.57 kpc and to estimate a color excess E(B-V) = 0.66 mag. Using IPHAS data we identified 32 objects that would have emission of H_α, of which 21 would be Be star candidates.
