      Explanation: On October 14 it was hard to capture a full view of Comet   
      C/2023 A3 Tsuchinshan-ATLAS. Taken after the comet's closest approach   
      to our fair planet, this evening skyview almost does though. With two   
      telephoto frames combined, the image stretches about 26 degrees across   
      the sky from top to bottom, looking west from Gates Pass, Tucson,   
      Arizona. Comet watchers that night could even identify globular star   
      cluster M5 and the faint apparition of periodic comet 13P Olbers near   
      the long the path of Tsuchinshan-ATLAS's whitish dust tail above the   
      bright comet's coma. Due to perspective as the Earth is crossing the   
      comet's orbital plane, Tsuchinshan-ATLAS also has a pronounced   
      antitail. The antitail is composed of dust previously released and   
      fanning out away from the Sun along the comet's orbit, visible as a   
      needle-like extension below the bright coma toward the rugged western   
      horizon.
