Right Acsension (RA) is in hours & minutes. Declination (Dec) is in degress. Though the Dec settings will be in degrees as a whole, anything smaller than a degree will be in minutes and seconds. Example: RA 4hr 30min Dec 37deg 30min. In the Dec example 37deg & 30min means 37 and a half. 30 minutes equals half of a degree. I pretty sure your setting circles on your scope only go to minutes at a minimum. I wouldn't worry about the seconds on a 4500. Polaris or North Star as it's called is close to the "north pole". It's coordinates are RA 0hr +90 0hr. If you were to use a T-Square and point one end at polaris and the other end up. The end up is 0 degrees or celestial equator. I hope this helps a little.
