150mm f/17.6 refractor by Tully 1827
A wide double star on the north extreme of the tail; whence it was called Dheneb Kaïtos shemálí, the northern branch of the Whale's tail. A 4, bright yellow; B 15, deep blue. This is an excessively difficult object, being only discernible after long attention, and by occasionally averting the eye to another part of the field in view. The position and distance are therefore only the result of cautious estimation. It is No. 1953 of H.'s Fifth Series, where the companion is rated as of the 12th magnitude. There is a small star near the vertical, in the sp quadrant. The proper motion of A has been deduced by reference to standard Catalogues, from which it was thus valued:Flamsteed . .RA + 0".161 Dec. + 0".08and by Mr. Daily's recent deductions, its amount is, in RA +0".02, and in Dec. -0".05. The object may be found by a line carried through α Andromedae and γ Pegasi, and extended to about 24° south of the latter, where it will be seen as the north-eastern apex of a nearly equilateral triangle formed by ι, η, and β Ceti.
