    RICH-FIELD _telescope is an in-strument that covers a fair1 largesegment of the sky and has goo8 light-gathering ability. For viewing nebulae,the Milky Way and the moon, it can t besurpassed. The best RFT (richest-fieldtelescope) of the reflecting type is onehaving a 7-inch diameter mirror of f-4

    value or about 59-inch focal length. Afairly long eyepiece of at least one inchor more in focal length should be used.Inasmuch as Pyrex telescope blanksdo not come in seven-inch diameters,the eight-inch diameter was sekcted:To reduce diffraction effects a bit, f-5was selected [Continued on pug 1901

    tube is found by balancing the tube com-plete with mirror and eyepiece) on theedge of a 2x4. Mark the point of balanceand exactly on the opposite side of the tel-escope tube mark a second point. Thesepoints locate the declination axes. Set upthe different parts for each declinationbearing as shown in the declination bearingdetail and balance the telescope tube in thecradle. The cradle and piers should bebuilt first.) Balancing the telescope tubeat this time will prevent it from leaningto one side or the other while it is looselymounted on the two piers. P ress wooddough or plastic wood all around in thespace on one side of the telescope tubebetween the plywood disk and the tele-scope tube. Repeat the operation in.thespace on the other side. Allow two orthree days for the wood dough to harden.

    The cradle can be adjusted so the partsare on the same plane by pressing thecradle against a flat surface before the nutsget a final tightening. The diagonal holderis the four-vane type. Half-inch metalstrap, as used in shipping cartons, is usedfor the vanes. This st rap is discarded byhardware stores and may be. had for theasking.Place plastic bowl covers over the topof the telescope tube, eyepiece extensionholder and- he maple disk when the tele-scope is not in use.75 POWER TELESCOPE 53.98VARIABLE EYEPIECE 25X-45X-75X--BRAS.S BOUNIn -l xl gh t lrnnpen with 4 5 andlor e x t r a long ranxt.
