On March 15, 2000, a discussion thread began in the sci.astro.amateur (SAA) newsgroup when someone posed the question: “What are your favorite non-Messier objects for 8-12″ telescopes?” Newsgroup participants responded enthusiastically to the question, posting many messages nominating a wide variety of objects.

Fortunately, newsgroup participant Karl Hutchings kept a cumulative list of all the nominations and totaled the number of votes for each object. When the discussion thread wound down a few days later, Karl posted a list of 90 objects that SAA participants had named as their favorites.
