    • Searching for a Variable star

      The possible candidates should have the following characteristics:

      • magnitude difference between minimum and maximum > 0.5 mag
      • a sufficiently short period so that it can be observed during a single session (a few hours)
      • visible during these days and preferably in the early part of the night (we will observe starting from 21:30 onward)
      • limiting magnitude of 15 (note that with the Basovizza telescope, using a 30-second exposure, we can reach about magnitude 17, but it is better to work with somewhat brighter objects)
      • preferably far from the Moon 🌙

      You can consult the websitewww.aavso.org, in particular the search page
      https://www.aavso.org/vsx/index.php?view=search.top. Any other search method/site is also fine—the important thing is the result! ⭐

      If you would also like to practice preparing finding charts (perhaps for the object you consider the most suitable), you can try using this site:
