      Survey the observing field at any star party or convention, and you'll
      see what equipment today's amateur astronomer desires. Modern
      apochromats are common, and often set up for imaging. There are usually
      many Dobsonians, some of large aperture, and a variety of other
      telescopes. But the classic f/15 achromat is a rarity.

      Clear skies, Alan
