While the R.A. setting circle tracks with the drive motor, it does not move when slewing the telescope. Unlike other methods that require you to find the celestial pole by identifying certain stars near it, this method works off of a known constant to determine how high the polar axis should be pointed. Once again, make the appropriate adjustments to the polar axis to eliminate any drift.
Dim The DIM button changes the intensity of the LED displays. The star should be approximately ± 1/2 hour of the meridian and ±5° of the celestial equator. The North Celestial Pole is the point in the northern hemisphere around which all stars appear to rotate. One on top and one in the back of the mount. The motors on the mount are of a type called stepper. Backlash) Compensation The TVC (Time Variable Compensation) function allows you to eliminate the backlash in the DEC motor when changing directions such as from north to south or vice versa.
Sidereal rate is based on a single rotation of the Earth which takes 1,432.5 minutes. Declinations south of the equator carry a minus sign (-) in front of the coordinate and those north of the celestial equator are either blank (no designation) or preceded by a plus sign (+). The celestial equivalent of longitude is called Right Ascension, or R.A. for short. The size of the circular path a star follows depends on where it is in the sky. Second, grab hold of the DEC housing or saddle plate depending on which axis you are working. Apply some grease on the threaded part of the shaft were the clutch knob screws.
