Nonetheless, this is the first I&#8217;ve gotten a decent image of the half-phase, and had to play around a lot with exposure to get it &#8211; you know how bright Venus is in the sky, so this is considerably less exposure time than the moon itself. 1\/125 for the moon, 1\/800 for Venus, both at f14, ISO 1600.<\/p>\n<p>Yet <em>those<\/em> weren&#8217;t the primary thing that I was out there after, which is instead this<strong>:<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/wading-in.net\/walkabout\/wp-content\/uploads\/2023\/06\/MarsCancerCluster.jpg\" alt=\"Mars within M44 Beehive Cluster, Praesepe, NGC 2632, Cr 189\" width=\"750\" height=\"911\" class=\"aligncenter size-full wp-image-34558\" \/><br clear=\"all\"\/>This is Mars among the stars of M44, also known as the Beehive Cluster, Praesepe, NGC 2632, and Cr 189, because it&#8217;s got a rap sheet as long as your arm. In checking out Stellarium the other night I saw that Mars would be right in the middle of this cluster within the constellation of Cancer, and since we had clear skies I had to give it a shot. Right offhand, I don&#8217;t know why Mars was as dim as this, appearing only as bright as some of the common stars and not at all like a planet. The stars seen here, however, were pretty dim, only resolved through the long lens largely because of that nearly-full moon lighting up the sky.
