    Celestaire offerings
    From: Rick Emerson

    A couple new entries in Celestaire's catalog caught my attention.
    First, Sven Lundin's pocket sextant is being offered for $65.  This
    isn't one of those Indian-made Stanley reproductions but a set of
    reflecting bits of glass which use a 35 mm film can as a carrying
    case(!).  See the description for the details.
    Three book titles also stood out during my browsing.  Recalling the
    discussion here about lunars, take a look at "Tables for Clearing the
    Lunar Distance" by Bruce Stark (soft cover, spiral bound, 301 pp.,
    $37).  "Compact Sight Reduction Table" by Allan E. Bayless (soft
    cover, 32 pp., $6) is a compact version of the HO 211 tables.
    Compression is achieved by omitting every other entry in the tables.
    The third title prompts a question about "how's it done".  "Celestial
    Navigation with the S-table" by Mike Pepperday (soft cover, 30 pp.,
    $9.95) has "...the only tables to yield the same results as a
    navigation computer; that is they give intercepts directly from a DR
    position."  Can someone explain why most paper reduction processes
    work from an assumed position which isn't the DR position?
    Celestair is at 800-727-9785 or 316-686-9785 or
