K eep the tripod legs at their shor test (fully retracted) length, f or now; you can e xtend them to a more desirab le length later, after the scope is fully assemb led. 2.

The telescope is now balanced on the right ascension axis. Now when y ou loosen the lock lev er on one or both axes and manually point the telescope, it should mov e with - out [...]

7 Aligning the Finder Scope The SkyVie w Pro 80mm ED EQ comes with a 8x40 achromat- ic finder scope (Figure 3a).

Stars in the Norther n Hemisphere appear to re volve around the NCP . T o find P olaris in the sky , look nor th and locate the patter n of the Big Dipper (Figure 9). The two stars at t[...]

Now , sight P olaris in the polar axis finder scope . If y ou hav e f ol lowed the approximate polar alignment procedure accurate- ly , P olaris will p[...]

11 appear to mov e faster at higher magnifications, because the field of view is narro wer . Optional Motor Drives for Automatic T racking An optional DC motor driv e can be mounted on the R.A. axis of the equatorial mount to pro vide hands-free trac king. Objects will then remain stationar y in the field of view without any manual adjustment of th[...]

12 The setting circles must be re-calibrated e very time you wish to locate a new object. Do so by calibrating the setting circles f or the centered object before moving on to the ne xt one.

Cooling the T elescope All optical instruments need time to reach “th[...]

14 Even at par tial phases, the Moon is very bright. Use of an optional Moon filter to helps to dim the view . It simply threads onto the bottom of the ey epiece. Y ou’ll find the Moon filter improv es viewing comfort, and helps bring out the subtle fea- tures of the lunar surf ace. B. The Sun Y ou can change y our nighttime telescope into a dayt[...]

15 Determine in which constellation the object lies. Now , find the constellation in the sky . If y ou do not recogniz e the constella- tions on sight, consult a planisphere . The planisphere gives an all-sky view and shows which constellations are visible on a given night at a giv en time. Now , look at your star char t and find the br ightest sta[...]
