4 3. Assembly Assembly should tak e no more than 30 minutes. Refer to Figure 1 during assembly . Assembling the telescope requires no tools other than the ones provided. 1. Stand the tripod legs upright and spread the legs out as far as they will go .
5 place to keep the hand controller out of the w a y when not in use. Place the “hooks” str ip of n ylon adhesive on the bac k of the hand controller and the “loops” str ip on a tripod leg or on the mount where it will be in a conv eniently reached spot.
6 5. With one hand on the telescope optical tube, loosen the Dec. lock le v er . The telescope should now be ab le to rotate freely about the declination axis.
7 3a). Back the lock ring off by a f ew turns, f or now . Refocus the finder scope on a distant object by threading the objectiv e lens cell in or out of the finderscope body . Precise focusing will be achie ved by f ocusing the finder scope on a bright star .
8 Polar Alignment F or Nor thern Hemisphere obser v ers , appro ximate polar align- ment is achie ved by pointing the mount ’ s r ight ascension axis at the Nor th Star , or P olaris. It lies within 1 ° of the nor th celes- tial pole (NCP), which is an e xtension of the Ear th ’ s rotational axis out into space.
9 quick and easy . T o align the mount using the polar axis finder scope, f ollow these instructions: 1. Approximately polar-align the mount as outlined in the pro- cedure pre viously . 2. Loosen the Dec. lock le ver and rotate the optical tube on the declination axis so that the tube is at a 90 ° to the right ascension axis (Figure 10).
10 hand controller to “ N ” if you liv e in the norther n hemisphere, or “ S ” if you liv e in the souther n hemisphere. When you flip the power s witch, the pow er indicator light on the mount will glow red and the power indicator light on the hand controller will glow green.
Dec. setting circle until the pointer reads e xactly 90 ° .R e - tighten the setting circle thumbscrew . Calibrating the Right Ascension Setting Circle 1. Identify a bright star in the sky near the celestial equator (declination = 0 ° ) and look up its coordinates in a star atlas.
7. Collimating (Aligning The Mirr ors) Collimating is the process of adjusting the mirrors so they are aligned with one another . Y our telescope ’ s optics were aligned at the f actor y , and should not need much adjustment unless the telescope is handled roughly .
13 of the secondar y mirror . This is done by alternately loosening one of the three alignment set screws while tightening the other two , as depicted in Figure 16. The goal is to center the primar y mirror reflection in the secondar y mirror , as in Figure 14d.
14 Star-T esting the T elescope When it is dark, point the telescope at a br ight star and accu- rately center it in the e yepiece ’ s field-of-view . Slowly defocus the image with the f ocusing knob. If the telescope is correctly collimated, the e xpanding disk should be a perfect circle (Figure 19).
15 an hour or more. In the winter , stor ing the telescope outdoors in a shed or garage greatly reduces the amount of time need- ed f or the optics to stabilize. It also is a good idea to k eep the scope cov ered until the Sun sets so the tube does not heat greatly abov e the temperature of the outside air .
16 Important Note: Do not look at the Sun with any optical instrument without a prof essionally made solar filter , or permanent eye dama ge could result.
17 object, the lower its magnitude . Choose an object with a visu- al magnitude of 9 or lower . Many beginners star t with the Messier objects, which represent some of the best and bright- est deep-sky objects, first catalogued about 200 y ears ago by the F rench astronomer Charles Messier .
18 era ’ s shutter is now ready to be opened. A remote shutter release must be used or the image will be b lurred beyond recognition. T r y e xposure times between 1 and 10 seconds, depending upon the brightness of the planet to be pho- tographed and the ISO of the film being used.
19 with hard silicon dio xide, which prev ents the aluminum from o xidizing. These coatings nor mally last through man y y ears of use bef ore requir ing re-coating (which is easily done). T o clean the secondar y mirror , first remov e it from the tele- scope.
