The night sky is in continuous motion, and the two slow motion control knobs on the PowerSeeker mount will allow you to throughout the night. One know will control the mount on the right ascension (RA) axis while the other one will control the declination (DEC) axis. Once your mount is aligned on Polaris, the North Star, you will be able to point your favorite celestial object by moving both RA and DEC axis and, once your object is centered in the eyepiece, you will only have to move the RA axis to track it!
Included Accessories
The 20mm and 4mm eyepieces included with the telescope respectively provide you with a magnification of 50x and 250x. The 20mm eyepiece will best most useful for low powered views while the 4mm is dedicated to high power observation of the planets, of the Moon and of double stars. A 3x Barlow is also included and effectively triples the magnifying power of each eyepiece.
