The telescope is now balanced on the R.A. axis . It is not nec- essar y to balance the telescope on the Dec. axis, since the optical tube’ s mounting plate is positioned so that the tele - scope will automatically be balanced on that axis. When you loosen the lock le ver on one or both axes of motion and man- ually point the telescope, it should ...

The Polar Axis Finder Scope A nice feature of the StarMax 127 EQ is the polar axis finder scope housed inside the R.A. axis of the equator ial mount (see Figure 4). When properly aligned and used, it makes accurate polar alignment quic k and easy to do . Alignment of the polar finder need only be done once, unless it gets bumped or otherwise shifts ...

9 F or most accurate polar alignment, you will need to know the appro ximate longitude of your observing site . This inf or mation can be obtained by looking at a local map. Now , you must figure the diff erence between the longitude of y our observing site and the closest standard time meridian. The standard time meridians are 75°, 90°, 105°, a ...

10 The R.A. and Dec. values f or celestial objects can be found in any star atlas or star catalog. The R.A. setting circle is scaled in hours, from 1 through 24, with small marks in between representing 10 minute incre - ments (there are 60 minutes in 1 hour of R.A.). The upper set of numbers apply to viewing in the Nor ther n Hemisphere, while the ...

The k ey things to remember when pointing the telescope are, first that you only mov e it in R.A. and Dec., not in azim uth or latitude (altitude), and second, the counterweight and shaft will not alw ays appear as it does in Figure 1. In fact, it almost ne ver will! 6. Using Y our T elescope— Astr onomical Obser ving Choosing an Observing Site W ...
