Comet ISON was imaged the evenings of May 2nd and May 3rd, 2013 from Snowflake, AZ, by Bill Wood.  At magnitude 14.8, ISON was captured using a Canon EOS T3 DSLR set at ISO 6400 and 30 second exposure.  The DSLR was at prime focus on a small Orion ED80 f/7.5 APO refractor with tracking on an Orion Atlas GEM.  Maxim DL was used to combine each evening's 20 frames.  SkyTools 3 made capturing this unseen object possible by generating essential finder charts.
