@kuntzer, they might have included more recent catalogs than DSS to be used for the plot_target_on_sky function. Also, it is possible to query vizier catalogs to overplot the known objects on top of the finding chart - pretty cool feature to add in POUET if you ask me!
This issue is mostly informative. Astroquery just got updated and has a nice paper out.
