    Achromatic Telescope
    From: Andrew Corl
    Date: 2003 Oct 6, 17:46 -0400

    I was recently reading the journals of Lewis and Clark.  They mention taking several telescopes with them on their voyage.  Further research told me that one of the telescopes was an “Achromatic Telescope.”  Could anyone tell me (or refer me to a website) what this type of telescope is.  If there are plans available for this I would appreciate that link as well.  I am mainly interested in being able to see the moons of Jupiter (gives you an idea of the magnification I am looking for).
