Equipped with a deluxe equatorial mount, and aluminum tripod, the telescope’s motion is continuously adjustable for tracking celestial or land objects. Your telescope comes to you ready for adventure; it will be your companion in a universe of planets, breathtaking landscapes, galaxies, and stars. 1.This Manual These instructions detail the set-up, operation, specifications, and optional accessories of your Meade Model 395. In order that you may achieve maximum enjoyment of the instrument, we urge that you take a few minutes to read all of this manual before making first observations through the telescope. As you read this manual, the technical terms associated with telescopes will be made clear. 2. Standard Equipment • Complete optical tube assembly with multi-coated 90mm diameter objective lens, dew shield, cradle rings, viewfinder bracket, and 1.25" rack and pinion focuser. Lens focal length = 1000mm; f/11. • Equatorial mount with pre-attached heavy duty, continuously adjustable, aluminum tripod and leg braces. • Accessories: MA25mm (40x) eyepiece (1.25" O.D.) Diagonal mirror (1.25" O.D.) Counterweight with counterweight shaft Flexible cable controls for both telescope axes Accessory shelf with mounting knob 6 x 30 viewfinder B. Unpacking and Assembly (Numbers in brackets refer to Fig. 1, above) Your Meade Model 395 comes to you packaged almost entirely pre-assembled. You will find upon opening the giftbox that there are two compartments within that contain the optical tube assembly and the tripod with equatorial mount. The accessories described above will be located within compartments custom-cut into the styrofoam block inserts. (References herein-e.g. (6)-are to Fig. 1 unless otherwise specified.) • Remove and identify the telescope’s Standard Equipment listed in Section A.2., above. • The three tripod lock knobs (41) have been removed from the bottom section of each tripod leg to insure safe arrival of the tripod assembly. To install, thread in each tripod lock knob into the threaded hole located at the right side of each of the three gray colored castings (see illustration below) at the bottom of each tripod leg. Tighten the tripod lock knob only to a “firm feel” to avoid damage to the tripod caused by overtightening. • Spread the tripod legs (1) to full extension so that the leg braces (40) are taut (should one of the tripod leg braces slip out of the center triangle fastener, merely reposition the brace and slide it back into position). Adjust the tripod with the attached equatorial mount (2) to the desired height by loosening the tripod lock knobs and extend the sliding inner section of each tripod leg; then tighten each knob. • Remove the mounting knob (42) from the round accessory shelf. Place the accessory shelf on top of the center triangle leg brace fastener of the tripod so that the threaded stud protruding from the bottom of the accessory shelf (45) passes through the hole in the center. Then replace and tighten the accessory shelf mounting knob (42). • Attach the flexible cable controls (3) and (4). These cable controls are secured in place with a firm tightening of the thumbscrew located at the end of each cable. • The viewfinder bracket (38) comes pre-attached to the optical tube, but the viewfinder (24) is shipped separately. Place the viewfinder into the viewfinder bracket rings by backing off the thumbscrews. Then center the viewfinder in both bracket rings by backing off the three thumbscrews (26) on each bracket ring. Orient the viewfinder so its front objective lens is pointing in the same direction as the main -5- telescope’s objective lens (39). • Holding the counterweight (5) firmly in one hand, slip the counterweight onto the counterweight shaft (6). Attach the counterweight (5) and counterweight shaft (6), by supporting the unlocked (7) counterweight firmly in one hand, while threading the counterweight shaft into the base of the Declination axis of the telescope’s equatorial mount with the other (...
