What magnification range is often aimed for when trying to observe features like the polar caps or Sinus Meridiani?

Answer

Around 200x, potentially up to 400x if seeing is excellent.

Observers generally aim for a magnification around 200x to see features like the polar caps, though up to 400x might be attempted if the atmospheric seeing is sufficient to support it.
