Comets are among the more rewarding targets for astrophotography. Relatively short time exposures can drink in enough light to show a glowing coma – the gas and dust coming out of the comet as it warms in the vicinity of the sun – or even show a the comet’s tail as the solar wind blows these gases away from the comet itself. In these recent images, comet Lemmon displays its tail in the west-northwest, and comet SWAN is seen in a sea of stars in the southwest. Keep in mind that the nearest object in either picture is 56 million miles away, so set your focus accordingly!
