If you wear eyeglasses , you may be able to keep them on while you observe, if y our eyepieces ha ve enough “e ye relief ” to allo w you to see the whole field of view .
8 the Ear th’ s rotational (polar) axis—a process called polar alignment. Polar Alignment F or Nor ther n Hemisphere obser v ers, appro ximate polar alignment is achiev ed by pointing the mount’ s R.
9 Optional Motor Drives for Automatic T racking An optional DC motor drive can be mounted on the R.A. axis of the equatorial mount to provide hands-free trac king. Objects will then remain stationar y in the field of vie w without any manual adjustment of the R.
10 the counterweight shaft will be or iented somewhere between vertical and hor iz ontal. The ke y things to remember when pointing the telescope is that a) you only mov e it in R.A. and Dec., not in azimuth or latitude (altitude), and b) the counterweight and shaft will not alwa ys appear as it does in Figure 1.
11 If the entire primar y mirror reflection is not visib le in the sec- ondar y mirror , as in Figure 8c, you will need to adjust the tilt of the secondar y mirror . This is done by alter nately loosening one of the three alignment setscrews while tightening the other two , as depicted in Figure 10.
12 to see if the “dot” of the collimation cap is moving closer or fur ther aw ay from being centered in the “ring” of the pr imary mirror . When you ha ve the dot centered as much as pos - sible in the r ing, your primar y mirror is collimated.
13 ture change, the more time is needed. Allo w at least 30 min- utes for y our telescope to cool to the temperature outdoors. In very cold climates (below freezing), it is essential to store the telescope as cold as possible. If it has to adjust to more than a 40° temperature change, allo w at least one hour .
14 between the dark and light por tions of the disk (called the “terminator”). A full Moon is too br ight and de void of surf ace shadows to yield a pleasing view . Make sure to obser ve the Moon when it is well abov e the hor iz on to get the shar pest images.
15 brightest deep-sky objects, first catalogued about 200 years ago by the F rench astronomer Charles Messier . Determine in which constellation the object lies. Now , find the constellation in the sky . If y ou do not recognize the constella- tions on sight, consult a planisphere.
