Our metal Octants and Quadrants (sometimes called Half-Sextants) are liked by all who have used them, and for ordinary purposes of navigation are preferred by many to the full Sextant. They are handy and accurate and easy to read; the divisions are to 15′′ on the Octants and to 20 on the Quadrants; the Quadrants are preferred by most of our customers; for reliable instruments at a moderate price, they cannot be excelled. Each instrument is put up in a neat, square, mahogany box, with the necessary telescopes and fittings. No. 1, Octant, divided to 15", on silver..... $40.00 34.00 30.00 These cuts show the inner construction of the new prism system in these powerful glasses. It will be seen that this fourfold reflection is the secret of the compactness of the glass, and also of its fine definition and power. This arrangement of prisms also admits of a large field of view, the stereoscopic effect enabling the observer to distinguish distant objects and their surroundings, under the same magnification as in ordinary telescopes of equal power, the arrangement in ordinary telescopes being such that the more powerful they become the smaller becomes the field of vision. We can specially recommend the Trieder Binocular, being assured it will give entire satisfaction and will do all that is claimed for it.

It is of medium size (length closed 5 inches), good power, fine definition and large field; for every day use on board ship it cannot be excelled. Many glasses for which higher prices are charged will not give as much satisfaction as the "Neptune." Made in two sizes (24L and 26L object glasses) and in aluminum and metal frames. |
