Question

seeing is there is a way to view a star on the web by the RA and DEC coordinates

Answer 1

Sure. There are various digitized data sets all over the web. One I have often used is called skyview.

http://skyview.gsfc.nasa.gov/

I have only used the "professional" interface which is a bit complicated for the lay person. I suspect the novice interface will be very simple, but I don't know.
