Captain William Henry Smyth
Dec 24, 1831    No. 6 The Crescent, Bedford, England (map)
150mm f/17.6 refractor by Tully 1827

A Greenwich star of 1830, with a distant comes, on Castor's right instep; a glance from Orion's sword cluster through ζ, the lowest of the belt, carried closely to the east of Betelgeuze, and 16° beyond, will rest upon μ. A 3, crocus yellow; B 11, bluish; there are two other companions in the sf, and a group of small stars follow at Δ RA=25s. This object is known as Tejat post, from Tahyáh, a word used by the Arabs, as the name of a constellation formed by the two stars η and μ, in the anterior feet of Gemini, also called Al-hen'ah, and Al-nuhhátaï. The latter word is the dual of Nuhát, side or inclination; which affording but little clue, Nahátaï (from nahát) two strangers, has been suggested. The proper motion of the præses has been thus valued:

    P....   RA +0".13 Dec. -0".16
    B....      +0".15      -0".13
   [Hipparcos  +0".05639   -0".11003]
