Therefore, one of the most important ways to "beat the atmospheric seeing" is to give your telescope time to come to equilibrium with its surroundings. Amateurs … WebbStars “twinkle” more than the bright planets because they are so much more distant that they are effectively a point source. Their light gets smeared across a seeing disc a few arcseconds in diameter. Planets, with an angular diameter of ~10-30 arcseconds are extended sources and thus less affected.
