4 5. Orient the equator ial mount as it appears in Figure 1, at a latitude of about 40°, i.e., so the pointer next to the lati - tude scale is pointing to the line at “40”. T o do this, loosen one of the latitude adjusting T -bolts and then tighten the other latitude adjusting T -bolt until the pointer and the “40” line up .
thumbscrews on the housing, which is located at the rear of the R.A. axis . Inser t the front end of the polar finder (the end without the e yeguard) into the housing so only about 1" of the polar finder e xtends from the back of the housing. Do this slowly and with a twisting motion to pre vent the internal O-ring from becoming unseated.
6 Focusing the T elescope Y ou should now tr y to familiarize yourself with focusing the telescope. With the 25mm eyepiece inser ted in the diago - nal, point the telescope in the gener al direction of an object at least a 1/4 mile aw ay . With your fingers, slo wly rotate one of the focus knobs until the object comes into shar p focus.
7 mov ement of astronomical objects, thereb y keeping them from drifting out of the telescope’ s field of view while you’ re obser ving. This is accomplished by slo wly rotating the telescope on its right ascension (R.A.) axis, using only the R.A.
8 tripod so the telescope points north. There is a label bear- ing a large “N” at the base of the equatorial mount (Figure 8). It should be f acing nor th. The equatorial mount is now approximately polar-aligned for casual observing. More precise polar alignment is required f or astrophotograph y and for use of the man ual setting circles.
9 7. Rotate the mount 180° about the R.A. axis. Again, it may be conv enient to remov e the counterweights and optical tube first. 8. Look through the polar finder again. Is the object being view ed still centered on the crosshairs? If it is, then no fur- ther adjustment is necessary .
10 Understanding the Setting Circles The setting circles on an equatorial mount enable y ou to locate celestial objects b y their “celestial coordinates”. Every object resides in a specific location on the “celestial sphere”. That location is denoted b y two numbers: its right ascension (R.
11 Depending on the altitude of the object you want to observe, the counterw eight shaft will be oriented some where between vertical and hor iz ontal. Figure 10 illustrates how the telescope will look when pointed at the f our cardinal directions: north, south, east and west.
12 Calculating Magnification (Power) T o calculate the magnification, or power , of a telescope with an e yepiece, simply divide the focal length of the telescope by the f ocal length of the eyepiece:.
13 What to Expect So what will y ou see with your telescope? Y ou should be able to see bands on Jupiter , the r ings of Satur n, craters on the moon, the waxing and waning of V enus, and possibly hun - dreds of deep sky objects.
14 as with any new task, that starhopping may seem challenging at first, but will become easier o ver time and with practice . T o starhop , only a minimal amount of additional equipment is necessar y . A star char t or atlas that shows stars to at least mag - ni tud e 5 is re qui red .
15 8. Collimation The AstroView 100 EQ telescope has objectiv e lens cell which incor porates a collimation adjustment; this helps to ensure peak optical performance.
16 Bef ore cleaning with fluid and tissue, blow an y loose particles off the lens with a b lower bulb or compressed air . Then apply some cleaning fluid to a tissue, nev er directly on the optics. Wipe the lens gently in a circular motion, then remove any e xcess fluid with a fresh lens tissue.
