4 4. Next, tighten the wingnuts at the top of the tripod legs, so the legs are securely f astened to the equatorial mount. Use the wrench and your fingers to do this . 5. Or ient the equatorial mount as it appears in Figure 1, at a latitude of about 40°, i.
See P ar t 4 for more inf or mation about the R.A. and decli- nation ax es. 11. Install the polar axis finder scope into its housing inside the R.A. axis of the equatorial mount. First loosen the three thumbscrews on the housing, which is located at the rear of the R.
6 Now when y ou loosen the lock le ver on one or both ax es and manually point the telescope, it should mo v e without resist- ance and should not drift from where you point it. Focusing the T elescope Y ou should now tr y to familiarize y ourself with f ocusing the tel- escope.
7 time. That apparent motion is caused by the Earth’ s rotation (from west to east). An equatorial mount (Figure 6) is designed to compensate f or that motion, allowing y ou to easi- ly “track” the movement of astronomical objects , thereby keeping them from drifting out of the telescope’ s field of view while you’ re obser ving.
8 4. Mov e the tripod so the telescope tube (and R.A. axis) points roughly at P olar is. If you cannot see P olar is directly from your observing site, consult a compass and rotate the tripod so the telescope points nor th. There is a label bear- ing a large “N” at the base of the equatorial mount (Figure 8).
9 6. Look through the polar finder at a distant object (dur ing the da y) and center it in the crosshairs. Y ou may need to adjust the latitude adjustment T -bolts and the tripod position to do this. 7. Rotate the mount 180° about the R.A. axis. Again, it may be conv enient to remove the counterweights and optical tube first.
10 without any manual adjustment of the R.A. slow-motion con- trol. A motor dr ive system is necessary for astrophotog raph y . Understanding the Setting Circles The setting circles on an equatorial mount enable you to locate celestial objects by their “celestial coordinates”.
11 T o point the telescope to the east or west, or in other direc- tions, y ou rotate the telescope on its R.A. and Dec. axes . Depending on the altitude of the object you w ant to obser ve , the counterweight shaft will be oriented somewhere between vertical and hor izontal.
12 Calculating Magnification (Power) T o calculate the magnification, or power , of a telescope with an ey epiece , simply divide the f ocal length of the telescope by the f ocal length of the ey epie.
13 What to Expect So what will you see with y our telescope? Y ou should be able to see bands on Jupiter , the rings of Satur n, craters on the moon, the waxing and w aning of V enus, and possib ly hun- dreds of deep sky objects.

Then apply some cleaning fluid to a tissue, ne ver directly on the optics.
Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
