How can a polar Aligned Reflector telescope be used for tracking? - reflector telescope book
The manual suggests aligining the telescope Polaris, then only with the AR command to keep track of objects, and then goes into the field of view.
Is it possible that if the object near the celestial north pole. Take, for example, Saturn is somewhere in the progression and the telescope to Polaris, as it develops a person of Saturn, addressed without changing direction with the azimuth control.
The manual says that aligned with the Pole Star is not telescopic necessary, the azimuth direction or the direction of December and only the RA can be changed to touch to track objects.
I do not understand!
Thanks

Reflector Telescope Book How Can A Polar Aligned Reflector Telescope Be Used For Tracking?

Do not align the telescope Polaris - Align the shaft with the Polaris.
Some instruments have a special form the core of rheumatoid arthritis in that direction. In other telescopes to turn the telescope 90 degrees declination. Anyway, you have to physically move the telescope mount, so that the RA-axis points to the north celestial pole. Once you've done this, leave the right of assembly, where it is, and show the telescope tube, where you want. During this time you can moving object of RA axis of the telescope's only title.
The orders of the AR moves the telescope in a circular motion. Circles around Polaris, which is what you need to pursue.

After assembly, the right ascension axis aligned with the axis of the earth (that's what you do when you are near to align Polaris), then the rotation around the axis of the assembly of the AR is the same as the rotation of the earth. Wherever you point the telescope, turn the frame around its own axis of rheumatoid arthritis in the opposite direction of rotation of the Earth (with the correct speed) is fixed at the same point in the air.
You can change when the telescope points * RA and controls in December to * without changing the nature of the RA axis is aligned movement ...
Remember that if you want, aim the RA axis with Polaris, which is not necessarily the telescope itself. Many images with so-called "areas of polar alignment - just low-power telescopes that go during the RA-axis - to make it easier to align the axle with the CPN come (north celestial pole). If you are one of those who no matter where the telescope is pointed itself:)
Gary H is correct. Try it, you'll see.
The whole sky - the sun, moon, planets, stars - everything revolves around Polaris, in our view, once a day. Have you ever seen a picture of the long-exposure night sky? Polaris because it is very close to the axis is close to the north / south axis of rotation of the Earth is the only moving object, and all what is being described, to avoid him.
And what does your manual is that aligned to Polaris, then change the AR and December to find his destiny. Once you do follow, then, need only be adapted, RA
